Lattice-Based Cryptography
Most modern cryptography, and public-key crypto in particular, is based on mathematical problems that are conjectured to be infeasible (e.g., factoring large integers). Unfortunately, standard public-key techniques are often too inefficient to be employed in many environments; moreover, all commonly used schemes can in principle be broken by quantum computers. This talk will review my recent work on developing new mathematical foundations for cryptography, using geometric objects called lattices. Compared to more conventional proposals, lattice-based schemes offer a host of potential advantages: they are simple and highly parallelizable, they can be proved secure under mild worst-case hardness assumptions, and they remain unbroken by quantum algorithms. Due to the entirely different underlying mathematics, however, realizing even the most basic cryptographic notions has been a major challenge. Surprisingly, I will show that lattice-based schemes are also remarkably flexible and expressive, and that many important cryptographic goals can be achieved --- sometimes even more simply and efficiently than with conventional approaches. Some of our schemes provide interesting twists on old and cherished cryptographic notions, while others introduce entirely new concepts altogether.

Pairing-based proof systems and applications to anonymous credentials
Pairing based cryptography has resulted in a number of breakthrough results, including some major developments in the area of zero knowledge proof systems. A zero knowledge proof system allows a party to prove that a statement is true without revealing any other information. Zero knowledge proofs are used in everything from identification protocols (allowing a party to prove that he is who he claims to be) and encryption schemes with stronger security properties, to securing protocols against malicious adversaries, and constructing privacy preserving systems. It has been shown that zero knowledge proofs can be constructed from a variety of number theoretic assumptions (or, more generally from any trapdoor permutation); however most of these constructions are complex and inefficient. In '06 Groth, Ostrovsky, an Sahai showed how to construct proof systems based on pairings which have much more structure than traditional constructions; this structure in turn has since been shown to result in proof systems with greater efficiency, stronger security, and more functionality. This talk will describe at a high level how pairings allows us to construct zero knowledge proofs with more structure than traditional tools, and then discuss some of the applications that take advantage of this structure, focusing on applications to privacy and anonymity.

Bitcoin Q&A: Migrating to post-quantum cryptography
Keywords/phrases: Quantum cryptography, quantum cryptoanalysis, quantum computing. Bitcoin uses SHA-256. In cryptography there is a 20-30 year lifecycle for an algorithm before it gets exceeded by new technologies and developments in mathematics. Both the signing and hashing algorithms can be upgraded in Bitcoin if there is a need to do that. Quantum cryptography represents a threat only if unevenly distributed in commercial sectors. If it is available to only one actor, and not all actors, they are unlikely to use it against Bitcoin; instead they're going to keep it secret and use it when they're threatened by ex. cryptographically secure nuclear weapons. Intelligence agencies who have that kind of significant computing advantage don't use it until there is a dire emergency, because once you use it everyone will know you have it. After that all the algorithms get changed, so you better make it good. If it is widely available, all the miners update to quantum computers and we're going to be looking at several orders of magnitude in improvement, because running one is neither free nor easy. We don't know what the economics will be yet, but we will solve problems when it's necessary. Corporations and governments are not going to be happy with Bitcoin. Kings were not happy and yet the revolution happened anyway. Bitcoin is a global and technological revolution. They have adapted to new technologies for hundreds of years. The fact that they won't be happy doesn't concern me, because Bitcoin is a system that doesn't require their permission, approval, or cooperation. They can pretend it's going away but it isn't. We can talk all day about whether the government should or shouldn't regulate Bitcoin, but the real question is whether they can. They can regulate at the edge, the behaviour of users, but they can't regulate Bitcoin itself. Bitcoin is exciting because it introduces a new choice; it's not saying you can't do the old way (hierarchical central banking, border-restricted jurisdictions for currencies ), it's saying we can also do this.

Post-Quantum Zero-Knowledge and Signatures from Symmetric-Key
We propose a new class of post-quantum digital signature schemes that: (a) derive their security entirely from the security of symmetric-key primitives, believed to be quantum-secure, and (b) have extremely small keypairs, and, (c) are highly parametrizable. In our signature constructions, the public key is an image y=f(x) of a one-way function f and secret key x. A signature is a non-interactive zero-knowledge proof of x, that incorporates a message to be signed. For this proof, we leverage recent progress of Giacomelli et al. (USENIX'16) in constructing an efficient sigma protocol for statements over general circuits. We improve this sigma protocol to reduce proof sizes by a factor of two, at no additional computational cost. While this is of independent interest as it yields more compact proofs for any circuit, it also decreases our signature sizes. We consider two possibilities for making the proof non-interactive, the Fiat-Shamir transform, and Unruh's transform (EUROCRYPT'12,'15,'16). The former has smaller signatures, while the latter has a security analysis in the quantum-accessible random oracle model. By customizing Unruh's transform to our application, the overhead is reduced to 1.6x when compared to the Fiat-Shamir transform, which does not have a rigorous post-quantum security analysis. We implement and benchmark both approaches and explore the possible choice of f, taking advantage of the recent trend to strive for practical symmetric ciphers with a particularly low number of multiplications and end up using LowMC. This is joint work with Melissa Chase, David Derler, Steven Goldfeder, Claudio Orlandi, Christian Rechberger, Daniel Slamanig and Greg Zaverucha.  See more on this video at https://www.microsoft.com/en-us/research/video/post-quantum-zero-knowledge-and-signatures-from-symmetric-key/

Cryptographic Program Obfuscation: Current Capabilities and Challenges
Cryptographic program obfuscation (CPO) enables the evaluation of obfuscated programs/circuits for non-encrypted inputs using cryptographic approaches based on standard (or almost standard) security assumptions. CPO is a hot topic of cryptography that has recently seen remarkable progress, fueled by the DARPA SafeWare program. CPO has a lot of potential high-impact applications for the defense industry, specifically in classification problems and other areas of machine learning. Many recent advances in CPO have come from the cryptographic primitives based on lattices. This talk reviews some of these advances and current capabilities/applications of lattice-based CPO protocols from the perspective of PALISADE, an open-source lattice cryptography library that is being developed by the NJIT Cybersecurity Research Center in collaboration with its partners in academia, government, and industry. The current challenges limiting the practicability of CPO are also discussed.

Charles River Crypto Day - The Power of Negations in Cryptography
The study of monotonicity and negation complexity for Boolean functions has been prevalent in complexity theory as well as in computational learning theory, but little attention has been given to it in the cryptographic context. Recently, Goldreich and Izsak (2012) have initiated a study of whether cryptographic primitives can be monotone, and showed that one-way functions can be monotone (assuming they exist), but a pseudorandom generator cannot. In this work, we start by filling in the picture and proving that many other basic cryptographic primitives cannot be monotone. We then initiate a quantitative study of the power of negations, asking how many negations are required. We provide several lower bounds, some of them tight, for various cryptographic primitives and building blocks including one-way permutations, pseudorandom functions, small-bias generators, hard-core predicates, error-correcting codes, and randomness extractors. Among our results, we highlight the following. i) Unlike one-way functions, one-way permutations cannot be monotone. ii) We prove that pseudorandom functions require log n−O(1) negations (which is optimal up to the additive term). iii) Error-correcting codes with optimal distance parameters require log n−O(1) negations (again, optimal up to the additive term). iv) We prove a general result for monotone functions, showing a lower bound on the depth of any circuit with t negations on the bottom that computes a monotone function f in terms of the monotone circuit depth of f. This result addresses a question posed by Koroth and Sarma (2014) in the context of the circuit complexity of the Clique problem. Joint work with Siyao Guo, Igor Carboni Oliveira, and Alon Rosen.

Great Crypto Failures
This paper was presented by Yaniv Balmas and Ben Herzog (Check Point Software Technologies) at VB2016 in Denver, CO, USA. "There is a theory which states that if ever anyone discovers exactly how to properly use cryptography, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened." Cryptography is no longer a niche malware feature. It has become the weapon of choice to subject victims to extortion, perform covert communications, achieve stealth and much more. Almost no crimeware bag of tricks is complete without a nasty ransomware binary somewhere in it. Like any other dangerous weapon, cryptography should be handled with care; in the wrong hands, it can easily become a double-edged sword — and, in fact, it does. There appears to be no upper bound for how ill-designed cryptography can be. Whenever you think you have seen the worst of it... well, you better think again. Our talk will showcase several real-world cryptographic disasters encountered by our researchers. Some are more well-known than others, but all have had consequences — for the attacker as well as their victims. Trying to extract value from these failures is often a crapshoot. In some cases, there is not much to do but to watch cryptography fail and laugh/cry. However, in other cases — especially if you know what to look for — you may be able to use cryptographic failures to your advantage and subvert the original intent of the malware to your benefit. This presentation will try to educate the audience on the common methods that can be employed to identify those failures, and perhaps save yourself, or others, from a very sticky situation. Points to be discussed during the presentation: * A technical overview of the uses of cryptography in modern malware. * Learn by example: Real-life cases of common mis-usages in cryptographic implementations, such as: bootleg homebrew crypto, key reuse, mishandling modes of operation, key mismanagement, weak encryption parameters. * Methods of detection: What can be done to detect these cryptographic gaffes? How does a human approach this without resorting to huge mathematical formulas? * Ways to take action: How can one take advantage of these failures and turn the tables on cybercriminals? https://www.virusbulletin.com/conference/vb2016/abstracts/great-crypto-failures

Fiat Cryptography: Automatic Correct-by-Construction Generation of Low-Level Cryptographic Code
Some of the most widely used cryptographic protocols, including TLS, depend on fast execution of modular big-number arithmetic. Cryptographic primitives are coded by an elite set of implementation experts, and most programmers are shocked to learn that performance-competitive implementations are rewritten from scratch for each new prime-number modulus and each significantly different hardware architecture. In the Fiat Cryptography project, we show for the first time that an automatic compiler can produce this modulus-specialized code, via formalized versions of the number-theoretic optimizations that had previously only been applied by hand. Through experiments for a wide range of moduli, compiled for 64-bit x86 and 32-bit ARM processors, we demonstrate typical speedups vs. an off-the-shelf big-integer library in the neighborhood of 5X, sometimes going up to 10X. As a bonus, our compiler is implemented in the Coq proof assistant and generates proofs of functional correctness. These combined benefits of rigorous correctness/security guarantees and labor-saving were enough to convince the Google Chrome team to adopt our compiler for parts of their TLS implementation in the BoringSSL library. The project is joint work with Andres Erbsen, Jade Philipoom, Jason Gross, and Robert Sloan.  See more at https://www.microsoft.com/en-us/research/video/fiat-cryptography-automatic-correct-by-construction-generation-of-low-level-cryptographic-code/

Original post: https://www.gcppodcast.com/post/episode-123-post-quantum-cryptography-with-nick-sullivan-and-adam-langley/ Nick Sullivan, and Adam Langley join Melanie and Mark to provide a pragmatic view on post-quantum cryptography and what it means to research security for the potential of quantum computing. Post-quantum cryptography is about developing algorithms that are resistant to quantum computers in conjunction with “classical” computers. It’s about looking at the full picture of potential threats and planning on how to address them using a diversity of types of mathematics in the research. Adam and Nick help clarify the different terminology and techniques that are applied in the research and give a practical understanding of what to expect from a security perspective.
Intervalue ICO AMA with CryptoArnie | The Underdog 4.0 DAG Project Rivaling Hashgraph, IOTA & Seele
Website: http://www.inve.one/ Intervalue Telegram: https://t.me/joinchat/HFJWYxCcv_bhLzTrdfzmGQ CryptoArnie Telegram: https://t.me/CryptoArniePublic What is InterValue? The InterValue project focuses on the core technology of Blockchain infrastructure and platform level. The goal is to build the underlying infrastructure covering all fields at the ecological level, which conquers the key technical problems. Main Technological Innovation (1)In the communication layer of the underlying P2P network node: The original anonymous P2P communication network is realized by combining the existing Tor-based anonymous communication network, the Blockchain-based distributed VPN and the advantages of the Blockchain-based distributed content sharing network. The protocol of node anonymity access is designed, and the private encrypted communication protocol is realized. These two protocols greatly enhance the anonymity of nodes in the underlying communication network and ensure that the communication between nodes is hard to be traced and cracked. (2)At the underlying data structure Layer A new data structure with an enhanced directed acyclic graph (HashNet) is adopted, which greatly reduces the storage space required by the nodes and improves the efficiency and security of the underlying data storage. (3)At the consensus mechanism Layer We designed three different consensus mechanism: a HashNet based consensus mechanism, BA-VRF consensus mechanism, basic DAG consensus mechanism. A consensus mechanism based on HashNet to enhance the consensus of DAG and BA-VRF consensus mechanism for notary selection is presented. In project version 1.0, due to the fact that HashNet-based DAG consensus is more difficult to implement, we first implement a two-Layer consensus mechanism that combines DAG consensus with BA-VRF. These consensuses all support high transaction concurrency, fast transaction confirmation speed, and building eco-systems for different application scenarios. (4)At the Layer of anti-quantum attack New anti-quantum algorithms are adopted, which replaces the existing SHA series algorithm with the Keccak-512 hash algorithm, and replaces the ECDSA signature algorithm with an integer lattice-based NTRUsign signature algorithm. These algorithms reduce the threat which brings from the quantum computing development and gradual popularization of a quantum computer. (5)At the Layer of anonymous transaction Combined with the characteristics of cryptocurrency such as Monroe and ZCash, the zero-knowledge proof and ring signature are used to design transaction anonymity and privacy protection method with high effective cost ratio and excellent security to meet privacy requirements of different application scenarios. (6)At the Layer of smart contracts We adopt the Turing comprehensive contract with fair distribution mechanism and support the issuance of third-party assets, which can take place in the form of the public Blockchain, permission (private) Blockchain, consortium (hybrid) Blockchain to the actual application scenario. (7)At the Layer of cross-link communication and multi-chain fusion The use of relay chain technology to cross-chain communication and multi-chain fusion function module as a single layer overlay to achieve, not only can maintain the independence of cross-chain operation, but also reuse InterValue basis chain Various functions. (8)At the ecologically motivated Layer Various Token allocation tools and methods are used in combination and support for double-layer mining for miners' incentives. (9)At the industry application level The development of JSON-RPC industry common interfaces, such as circulation payment, data transmission, data search, and contract invocation, supports various applications at the upper level.

Homomorphic Encryption from Ring Learning with Errors
The prospect of outsourcing an increasing amount of data storage and management to cloud services raises many new privacy concerns that can be satisfactorily addressed if users encrypt the data they send to the cloud. If the encryption scheme is homomorphic, the cloud can still perform meaningful computations on the data, even though it is encrypted. In fact, we now know a number of constructions of fully homomorphic encryption schemes that allow arbitrary computation on encrypted data. In the last two years, solutions for fully homomorphic encryption have been proposed and improved upon, but all currently available options seem to be too inefficient to be used in practice. However, for many applications it is sufficient to implement somewhat homomorphic encryption schemes, which support a limited number of homomorphic operations. They can be much faster, and more compact than fully homomorphic schemes. This talk will focus on describing the recent somewhat homomor- phic encryption scheme of Brakerski and Vaikuntanathan, whose security relies on the ring learning with errors (RLWE) problem.

Multiparty Computation Research
In this talk I will cover two topics. I will present MPyC, an open-source Python framework for rapid prototyping of MPC protocols, which is being developed at TU Eindhoven. Also, I will present a new MPC protocol for securely solving a full-rank linear system over the rational numbers. More precisely, given a square full-rank matrix with integral coefficients, whose elements are secret-shared among multiple parties, the parties’ goal is to compute the inverse (over Q) in secret-shared form, without leaking any information. Finally I will demonstrate the usefulness of MPyC in practice, by means of explaining step-by-step the MPyC-implementation our new protocol for secure linear algebra.

A Framework for the Sound Specification of Cryptographic Tasks
Nowadays it is widely accepted to formulate the security of a protocol carrying out a given task via the 'trusted-party paradigm,' where the protocol execution is compared with an ideal process where the outputs are computed by a trusted party that sees all the inputs. A protocol is said to securely carry out a given task if running the protocol with a realistic adversary amounts to 'emulating'' the ideal process with the appropriate trusted party. In the Universal Composability (UC) framework the program run by the trusted party is called an /ideal functionality/. While this simulation-based security formulation provides strong security guarantees, its usefulness is contingent on the properties and correct specification of the ideal functionality, which, as demonstrated in recent years by the coexistence of complex, multiple functionalities for the same task as well as by their 'unstable' nature, does not seem to be an easy task. In this work we address this problem, by introducing a general methodology for the sound specification of ideal functionalities. First, we introduce the class of /canonical/ ideal functionalities for a cryptographic task, which unifies the syntactic specification of a large class of cryptographic tasks under the same basic template functionality. Furthermore, this representation enables the isolation of the individual properties of a cryptographic task as separate members of the corresponding class. By endowing the class of canonical functionalities with an algebraic structure we are able to combine basic functionalities to a single final canonical functionality for a given task. Effectively, this puts forth a bottom-up approach for the specification of ideal functionalities: first one defines a set of basic constituent functionalities for the task at hand, and then combines them into a single ideal functionality taking advantage of the algebraic structure. We showcase our methodology by applying it to a variety of basic cryptographic tasks, including commitments, digital signatures, zero-knowledge proofs, and oblivious transfer. While in some cases our derived canonical functionalities are equivalent to existing formulations, thus attesting to the validity of our approach, in others they differ, enabling us to 'debug' previous definitions and pinpoint their shortcomings. This is joint work with Aggelos Kiayias (Univ. of Athens and Univ. of Connecticut) and Hong-Sheng Zhou (Univ. of Maryland).

Ray Perlner - Optimizing Information Set Decoding Algorithms to Attach Cyclosymmetric MDPC Codes
Ray Perlner of the National Institute of Standards and Technology presented a talk titled: Optimizing information set decoding algorithms to attack cyclosymmetric MDPC codes at the 2014 PQCrypto conference in October, 2014. Abstract: Recently, several promising approaches have been proposed to reduce keysizes for code based cryptography using structured, but non-algebraic codes, such as quasi-cyclic (QC) Moderate Density Parity Check (MDPC) codes. Biasi et al. propose further reducing the keysizes of code-based schemes using cyclosymmetric (CS) codes. While Biasi et al. analyze the complexity of attacking their scheme using standard information-set-decoding algorithms, the research presented here shows that information set decoding algorithms can be improved, by choosing the columns of the information set in a way that takes advantage of the added symmetry. The result is an attack that significantly reduces the security of the proposed CS-MDPC schemes to the point that they no longer offer an advantage in keysize over QC-MDPC schemes of the same security level. QC-MDPC schemes are not affected by this paper's result.

This task was set by the professor of the European Institute of Bioinformatics Nick Goldman who offered to read the keys within a cryptocurrency encrypted in this way, in order to receive 1 bitcoin as a reward. “The DNA contained: instructions how to get a bitcoin, the logo of the European Institute of Bioinformatics and some other things,” the author of the project said. “I had doubts about the possibility of using DNA to store data. But now I know very well that this new technology offers great opportunities, maybe even for my own future research,” he said. At the time of setting the task a bitcoin was cost about $329, and now its price is about $11,000.

Elliptic curves to the rescue: tackling availability and attack potential in DNSSEC
Speaker: Roland van Rijswijk-Deij, SURFnet Over the past decade, we have seen the gradual rollout of DNSSEC across the name space, with adoption growing slowly but steadily. While DNSSEC was introduced to solve security problems in the DNS, it is not without its own problems. In particular, it suffers from two big problems: 1) Use of DNSSEC can lead to fragmentation of DNS responses, which impacts the availability of signed domains due to resolvers being unable to receive fragmented responses and 2) DNSSEC can be abused to create potent denial-of-service attacks based on amplification. Arguably, the choice of the RSA cryptosystem as default algorithm for DNSSEC is the root cause of these problems. RSA signatures need to be large to be cryptographically strong. Given that DNS responses can contain multiple signatures, this has a major impact on the size of these responses. Using elliptic curve cryptography, we can solve both problems with DNSSEC, because ECC offers much better cryptographic strength with far smaller keys and signatures. But using ECC will introduce one new problem: signature validation - the most commonly performed operation in DNSSEC - can be up to two orders of magnitude slower than with RSA. Thus, we run the risk of pushing workload to the edges of the network by introducing ECC in DNSSEC. This talk discusses solid research results that show 1) the benefits of using ECC in terms of solving open issues in DNSSEC, and 2) that the potential new problem of CPU use for signature validation on resolvers is not prohibitive, to such an extent that even if DNSSEC becomes universally deployed, the signature validations a resolver would need to perform can easily be handled on a single modern CPU core. Based on these results, we call for an overhaul of DNSSEC where operators move away from using RSA to using elliptic curve-based signature schemes.

Daniel J. Bernstein - How to manipulate standards - project bullrun
Daniel J. Bernstein - How to manipulate standards - project bullrun Daniel Julius Bernstein (sometimes known simply as djb; born October 29, 1971) is a German-American[2] mathematician, cryptologist, programmer, and professor of mathematics and computer science at the Eindhoven University of Technology and research professor at the University of Illinois at Chicago. His computer software programs qmail, publicfile, and djbdns were released as license-free software. This was used by some of the people that were offended by his criticism to stop the distribution of his software, so that Linux distributions such as Debian which used qmail internally did not distribute qmail. OpenBSD a security focused operating system had the majority of its security exploits as a result of its decision to stay with Sendmail and BIND and removed qmail and djbdns from its ports as part of the license dispute. This issue was resolved when Bernstein released the source code of his projects into public domain software in 2007. Bernstein designed his Salsa20 stream cipher in 2005 and submitted to eSTREAM for review, another variant, ChaCha20, is published by him in 2008. He also designed Curve25519, a public key cryptography scheme based on elliptic curve in 2005, and worked as the lead researcher on its Ed25519 implementation of EdDSA. Without any adoptions at first, after nearly a decade later, Edward Snowden's disclosure about the mass surveillance by the National Security Agency, especially a backdoor inside Dual_EC_DRBG, suspicions of the NIST's P curve constants[3] led to concerns[4] that the NSA had chosen values that gave them an advantage in factoring[5] public keys.[6] Since then Curve25519 and EdDSA has attracted much attention and became the de facto replacement of NIST P curve. Google has also selected ChaCha20 along with Bernstein's Poly1305 message authentication code as a replacement for RC4 in TLS, which is used for Internet security.[7] Many protocols based on his works have now standardized and used in a variety of applications, such as Apple iOS,[8] Linux kernel,[9] OpenSSH,[10][11] and Tor.[12]

Random Access in Multiparty Computation
How can two strangers figure out how many phone contacts they have in common without revealing anything else about each other? Can this be done even in the absence of trusted third parties? How about the case of two strangers comparing genetic information to figure out how closely related they are? Many interesting applications have become possible with recent improvements in multiparty computation, and we are working to make it even more efficient and convenient to use. In this talk, we will be focusing on random memory access in secure computation. In other words, we will try to efficiently solve the problem where a program needs to access a memory location without revealing which location is being accessed. The first part will be on specialized circuit structures that allow extremely efficient memory access for any circuit-based protocol (e.g. Yao, GMW), but only if the access pattern follows certain constraints. The second half of the talk will be a new Oblivious RAM construction that allows any arbitrary random access, but is less efficient. Although this problem had been ``solved'' in theory, past solutions only provide asymptotic benefits. They all had exorbitant initialization costs which dwarfed any per-access performance improvement they provided. Our construction provides a 100x improvement in initialization cost, and concrete benefits for as small as 144 bytes of data, inspite of being asymptotically inferior. We hope this will make secure multiparty computation easier to adopt in a greater variety of applications than was reasonable in the past.

About this project : More details about the Fipsy FPGA are on our website Subscribe to our channel for latest and most popular technology videos everyday! http://bit.ly/2rDhAi1 Back and learn more about this project on Kickstarter : https://www.kickstarter.com/projects/1013562009/fipsy-the-fpga-breakout-board-for-beginners/ LEGAL NOTICE: We do not own this video, it belongs to its rightful owners. About anything please contact us via [email protected] If you want your product to be promoted and/or tested please contact us via [email protected] More about project : Advantages A very low price point for an introductory FPGA board. Other boards are closer to $60, which is too much of a price barrier for beginners. We are closer to $10. Designed for rapid prototyping – with a breadboard-compatible design Only uses free or open source design toolsSupported by numerous examples and guides from a DIY communityFPGAs fundamentally allow for ongoing, and adaptable hardware configurations and control, even once embeddedUnlike other FPGAs, this model does not lose is configuration on reboot FPGAs, or Field Programmable Gate Arrays allow a designer to program logic circuits at the hardware level, on the fly. This can greatly speed up processing or allow for massively parallel operations. FGPAs are described as a system designers ‘magical black bag’, in that they can be dynamically reconfigured to do any arbitrary type of digital processing. Sadly, FPGAs are a mysterious topic to most DIY tech-types. Specifically, the barriers to entry are the large learning curves, high costs, and limited open source examples.Our Fipsy FPGA device and learning material solves this issue head on!Background In 2016, our group was shocked to find that no cheap alternatives have existed since 2015 when the DISPY FPGA project was a finalist for 2015 Product of the Year. This project was inactive, so we revived it under the banner ‘Fipsy’. Now we have created numerous instruction guides, sample projects, and a commitment to on-going support and production. We are building exactly the board we wished we had when we were learning about FPGAs. The Kickstarter will launch a supply of DIY-friendly FPGA boards. Funding will be reinvested in purchasing additional boards so that cheap FPGAs will be available to all future makers. MoCo Makers supports the learning process with guides published on our website. The Fipsy Development Timeline What will we do with the money?With a the funds from this Kickstarter we will place a first batch order of Fipsy FGPAs. A successful campaign will allow future batches to be ordered as well, meaning we will have a perpetual stock of FPGAs to supply the hobbyist market! We have a working prototype sponsored by our manufacturer, Allied Component Works. Revenues will go towards the purchase of further batch orders, so that Makers everywhere can leverage the enormous benefits of FPGAs..Imagine the possibilities FPGAs can offer: Learn about FGPA/systems designI/O Port extenderGlue between different embedded systemsSoftware-based circuit configurationSimplified prototype boards, e.g. to wire up microcontrollers and periphery electronics on the flyDigital bus controllerPWM controller, e.g. for huge LED panelsFrequency generationReal-time modification of signal streams, such as HDMICreate neural network analogues Learning about FPGAsAll you need is the FGPA device, and you can learn from our guides Wiki ChatroomSet-up guide and instructionsExternal Learning ReferencesGet the Fipsy device, and you can apply an amazing and powerful electronics tool to your future projects! ...

Enforcing File Robustness in the Cloud; Efficient Verification of Outsourced Data and Computations
Segment II 11:10 am ΓÇô 12:30 pm Writing on Wind and Water: Enforcing File Robustness in the Cloud Ari Juels, RSA Laboratories The Cloud abstracts away infrastructural complexity for the benefit of tenants. But to tenants' detriment, it can also abstract away vital security information. In this talk, I discuss several protocols for remote testing of cloud storage integrity and robustness. Executing these protocols without detailed infrastructural knowledge or trust in cloud providers, clients or auditors can: (1) Verify the integrity of full files without downloading them; (2) Distribute files across cloud providers and ensure strong robustness with periodic, inexpensive checks (in a cloud analog to RAID); and (3) Test whether files are resilient to drive crashes. Joint work with Kevin Bowers, Marten van Dijk, Burt Kaliski, Alina Oprea, and Ron Rivest. Efficient Verification of Outsourced Data and Computations Charalampos Papamanthou, Brown University With the prevalence of the Internet in every aspect of our life, there has been an increasing interest in remote storage of data and structured information (e.g., emails, photos). This trend has given rise to a new discipline, termed under the name ΓÇ£cloud computing,ΓÇ¥ widely adopted by many companies (and individuals) in order to save operating and maintenance costs. However, as remote repositories (i.e., the cloud) may lose or modify data due to errors or malicious attacks, it is important to develop methods that provide strong assurance to the users of the integrity of the outsourced data. In order to address the above problems, one has to take into consideration that the produced solutions are efficient. In other words, if the security added to a cloud service leads to slow performance, the user might reject the service, since, although secure and trusted, the experienced overhead (time, bandwidth) by the service might be unacceptable. This talk explores integrity checking solutions that go beyond traditional hash-based methods, towards improving efficiency and achieving better asymptotic bounds. The systematic application of multiple cryptographic primitives, such as accumulators and lattices, leads to the proposal of new authenticated data structures schemes that compare favorably with existing solutions. We conclude by also reporting on some practical work we have done to address the aforementioned problems. This is joint work with Roberto Tamassia and Nikos Triandopoulos.

WACV18: Tutorial: Part 1: When Blockchain Meets Computer Vision: Opportunities and Challenges
Organizers: Karthik Nandakumar, Sharathchandra Pankanti, Nalini Ratha (IBM Singapore Lab; IBM Thomas J. Watson Research Center) Description: It is widely acknowledged that blockchain is foundational technology that will revolutionize the way transactions are conceived, executed, managed, and monetized. While the technological benefits of the blockchain infrastructure are imminent, the underlying technological problems need significant attention from researchers. Of specific interest to computer vision researchers and application developers is the opportunity to make a connection to these emerging infrastructure capabilities, and realize how their skills can be leveraged to make an impact. As the camera-based infrastructure is becoming ubiquitous and compute power is becoming pervasively available, the business world is going to look to camera as a default sensor, and camera-based analytics as a de facto information channel to improve the integrity of transactions. For instance, many complex practical challenges such as usability, compliance with regulations, integrity of transaction artifacts, and protecting privacy of sensitive information, can be effectively addressed using blockchain technology. The tutorial is aimed as a gentle introduction to the broader world of distributed transaction environment, and specifically blockchain technology. The tutorial will first introduce the blockchain technical concepts and capabilities in the context of real computer vision applications. The tutorial will subsequently review real application scenarios, where blockchain has tremendous potential to accelerate its use as an enterprise transaction infrastructure. The key technical challenges will be concretely couched in real mainstream use-cases such video surveillance and would cover many important aspects such privacy of end-users, scalability and cost-effectiveness, and user friendliness. Solving these problems requires multi-disciplinary research effort at the intersection of blockchain, artificial intelligence, and user behavior modeling.

A Secure and Efficient ID-Based Aggregate Signature Scheme for Wireless Sensor Networks
Abstract—Affording secure and efficient big data aggregation methods is very attractive in the field of wireless sensor networks research. In real settings, the wireless sensor networks have been broadly applied, such as target tracking and environment remote monitoring. However, data can be easily compromised by a vast of attacks, such as data interception and data tampering, etc. In this paper, we mainly focus on data integrity protection, give an identity-based aggregate signature scheme with a designated verifier for wireless sensor networks. According to the advantage of aggregate signatures, our scheme not only can keep data integrity, but also can reduce bandwidth and storage cost for wireless sensor networks. Furthermore, the security of our identity-based aggregate signature scheme is rigorously presented based on the computational Diffie-Hellman assumption in random oracle model.

Nathan Weibe seminar - Quantum arithmetic and numerical analysis using Repeat-Until-Success circuits
We develop a method for approximate synthesis of single--qubit rotations of the form e^{-i f(\phi_1,\ldots,\phi_k)X} that is based on the Repeat-Until-Success (RUS) framework for quantum circuit synthesis. We demonstrate how smooth computable functions, f, can be synthesized from two basic primitives. This synthesis approach constitutes a manifestly quantum form of arithmetic that differs greatly from the approaches commonly used in quantum algorithms. The key advantage of our approach is that it requires far fewer qubits than existing approaches: as a case in point, we show that using as few as 3 ancilla qubits, one can obtain RUS circuits for approximate multiplication and reciprocals. We also analyze the costs of performing multiplication and inversion on a quantum computer using conventional approaches and find that they can require too many qubits to execute on a small quantum computer, unlike our approach.
Understand the Blockchain in Two Minutes
Over the past decade, an alternative digital paradigm has slowly been taking shape at the edges of the internet. This new paradigm is the blockchain. After incubating through millions of Bitcoin transactions and a host of developer projects, it is now on the tips of tongues of CEOs and CTOs, startup entrepreneurs, and even governance activists. Though these stakeholders are beginning to understand the disruptive potential of blockchain technology and are experimenting with its most promising applications, few have asked a more fundamental question: What will a world driven by blockchains look like a decade from now?

2006-09-27 CERIAS - The Secure Information Sharing Problem and Solution Approaches
Recorded: 09/27/2006 CERIAS Security Seminar at Purdue University The Secure Information Sharing Problem and Solution Approaches Ravi Sandhu, George Mason University The secure information sharing problem is one of the oldest and most fundamental and elusive problems in information security. Mission objectives dictate that Information must be shared and made available to authorized recipients, and yet information must be protected from leakage and subversion by malicious insiders and malicious software. The doctrine of "share but protect" indicates the inherent conflict in achieving effective secure information sharing. In this talk we demonstrate the complexity and richness of the secure information sharing problem space. We then identify some "sweet spots" that appear promising in their practical benefit and feasibility of solutions. We describe the PEI models approach to decompose security problems into the three layers of policy models (topmost), enforcement models (middle), and implementation models (bottom). We discuss how this approach can be applied to the secure information sharing problem. Finally we indicate how modern trusted computing technology can be used to solve important variations of this problem. Dr. Ravi Sandhu earned B.Tech. and M.Tech. degrees from IIT Bombay and Delhi respectively, and M.S. and Ph.D. degrees from Rutgers University. He is a Fellow of ACM and IEEE, and recipient of the IEEE Computer Society Technical Achievement Award. His research has focused on information security, privacy and trust, with special emphasis on models, protocols and mechanisms. His doctoral work on safety and expressive power of access control was further developed by him culminating in the Typed Access Matrix in 1992. In collaboration with Prof. Jajodia, he analyzed and reconciled confidentiality and integrity in multilevel secure databases. In 1993 he showed that Chinese Wall separation of duty policies were instances of information flow. In 1996, along with industry colleagues, he published the seminal paper on role-based access control which evolved into the 2004 NIST/ANSI standard RBAC model. In 2002, with Jaehong Park, he introduced the Usage Control model for next-generation access. Other recent activities include Information Sharing models and implementations using Trusted Computing, and the PEI (policy, enforcement and implementation) layered models method for synthesizing secure systems. Ravi has published over 160 technical papers on information security, has received over 30 research grants and has graduated 12 PhD's in his career.Ravi is the founding editor of the Synergy Lecture Series on Information Security, Privacy and Trust. Earlier, he was the founding editor-in-chief of the ACM Transactions on Information and Systems Security (TISSEC), from 1997 to 2004. He was Chairman of ACM SIGSAC from 1995 to 2003, and founded and led the ACM Conference on Computer and Communications Security and the ACM Symposium on Access Control Models and Technologies to high reputation and prestige. He served as the security editor for IEEE Internet Computing from 1998 to 2004. In 2000 Ravi Sandhu co-founded the company now known as TriCipher and continues to serve as its Chief Scientist. He is the principal security architect of the TriCipher Armored Credential System. He is an inventor on eight security technology patents and has over fifteen patents pending. He is also the principal architect of the M.S. and Ph.D. programs in Information Security and Assurance at George Mason University. (Visit: www.cerias.purude.edu)

Role-based access control
In computer systems security, role-based access control (RBAC) is an approach to restricting system access to authorized users. It is used by the majority of enterprises with more than 500 employees, and can implement mandatory access control (MAC) or discretionary access control (DAC). RBAC is sometimes referred to as role-based security. This video is targeted to blind users. Attribution: Article text available under CC-BY-SA Creative Commons image source in video

Quantum computer
A quantum computer is a computation device that makes direct use of quantum-mechanical phenomena, such as superposition and entanglement, to perform operations on data. Quantum computers are different from digital computers based on transistors. Whereas digital computers require data to be encoded into binary digits (bits), each of which is always in one of two definite states (0 or 1), quantum computation uses qubits (quantum bits), which can be in superpositions of states. A theoretical model is the quantum Turing machine, also known as the universal quantum computer. Quantum computers share theoretical similarities with non-deterministic and probabilistic computers; one example is the ability to be in more than one state simultaneously. The field of quantum computing was first introduced by Yuri Manin in 1980 and Richard Feynman in 1982. A quantum computer with spins as quantum bits was also formulated for use as a quantum space--time in 1969. As of 2014 quantum computing is still in its infancy but experiments have been carried out in which quantum computational operations were executed on a very small number of qubits. Both practical and theoretical research continues, and many national governments and military funding agencies support quantum computing research to develop quantum computers for both civilian and national security purposes, such as cryptanalysis.

Field-programmable gate array
A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by a customer or a designer after manufacturing – hence "field-programmable". The FPGA configuration is generally specified using a hardware description language (HDL), similar to that used for an application-specific integrated circuit (ASIC) (circuit diagrams were previously used to specify the configuration, as they were for ASICs, but this is increasingly rare). Contemporary FPGAs have large resources of logic gates and RAM blocks to implement complex digital computations. As FPGA designs employ very fast I/Os and bidirectional data buses it becomes a challenge to verify correct timing of valid data within setup time and hold time. Floor planning enables resources allocation within FPGA to meet these time constraints. FPGAs can be used to implement any logical function that an ASIC could perform. The ability to update the functionality after shipping, partial re-configuration of a portion of the design and the low non-recurring engineering costs relative to an ASIC design (notwithstanding the generally higher unit cost), offer advantages for many applications.

General-purpose computing on graphics processing units
General-purpose computing on graphics processing units is the use of a graphics processing unit, which typically handles computation only for computer graphics, to perform computation in applications traditionally handled by the central processing unit. The use of multiple graphics cards in one computer, or large numbers of graphics chips, further parallelizes the already parallel nature of graphics processing. In addition, even a single GPU-CPU framework provides advantages that multiple CPUs on their own do not offer due to the specialization in each chip. Essentially, a GPGPU pipeline is a kind of parallel processing between one or more GPUs and CPUs that analyzes data as if it were in image or other graphic form. While GPUs generally operate at lower frequencies, they usually have many times more cores to make up for it and can, thus, operate on pictures and graphical data effectively much faster, dozens or even hundreds of times faster than a traditional CPU, migrating data into graphical form and then using the GPU to "look" at it and analyze it can result in profound speedup.
