Digital Signature : If the Sender Private key is used at encryption then it is called digital signature. This digital Signature is implemented two approaches 1) RSA Approach 2) DSS Approach.
What is digital signature?
A digital signature is equivalent to a handwritten signature in paper, and a digital signature serves three basic purposes. Digital signature is commonly used for software distribution, financial transactions and other cases where it is important to detect forgery. Digital signatures are very popular with e-mail users. In this video, I will talk about the digital, uses, and the whole process of creating and sending digitally signed document over the Internet. Keep in mind, digital signature is not about encrypting document, just like paper-based signature.

Top 5 Technologies
Top 5 Technologies in 2019 : https://youtu.be/aCY1GyKVpBw Python Tutorial for Beginners: https://goo.gl/cLKYQP 5 skills for IT Professional: https://goo.gl/ba6Ui7 Top 5 technologies to learn in 2018. Technologies are : IoT (Internet of Things) Cloud Computing Blockchain Artificial Intelligence Big Data IoT : The Internet of things (IoT) is the network of physical devices, vehicles, home appliances and other items embedded with electronics, software, sensors, actuators, and network connectivity which enables these objects to connect and exchange data. The IoT allows objects to be sensed or controlled remotely across existing network infrastructure. Cloud Computing: Cloud computing enables ubiquitous access to shared pools of configurable system resources and higher-level services that can be rapidly provisioned with minimal management effort, often over the Internet. Cloud computing relies on sharing of resources to achieve coherence and economy of scale, similar to a utility. Third-party clouds enable organizations to focus on their core businesses instead of expending resources on computer infrastructure and maintenance. Cloud providers typically use a "pay-as-you-go" model. Blockchain: A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography which is resistant to modification of the data. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data. Blockchains are secure by design and are an example of a distributed computing system The first blockchain was conceptualized in 2008 by an anonymous person or group known as Satoshi Nakamoto and implemented in 2009 as a core component of bitcoin where it serves as the public ledger for all transactions. Artificial intelligence: AI is intelligence displayed by machines. In computer science, AI research is defined as the study of "intelligent agents": any device that perceives its environment and takes actions that maximize its chance of success at some goal. Colloquially, the term "artificial intelligence" is applied when a machine mimics "cognitive" functions that humans associate with other human minds, such as "learning" and "problem-solving Big Data: Big data is data sets that are so voluminous and complex that traditional data processing application software is inadequate to deal with them. Big data challenges include capturing data, data storage, data analysis, search, sharing, transfer, visualization, querying, updating and information privacy. There are three dimensions to big data known as Volume, Variety and Velocity. Editing Monitors : https://amzn.to/2RfKWgL https://amzn.to/2Q665JW https://amzn.to/2OUP21a.

Machine-Checked Proofs of Privacy for Electronic Voting Protocols
Machine-Checked Proofs of Privacy for Electronic Voting Protocols Constantin Cătalin Drăgan (LORIA, CNRS & Inria) Presented at the 2017 IEEE Symposium on Security & Privacy May 22–24, 2017 San Jose, CA http://www.ieee-security.org/TC/SP2017/ ABSTRACT We provide the first machine-checked proof of privacy-related properties (including ballot privacy) for an electronic voting protocol in the computational model. We target the popular Helios family of voting protocols, for which we identify appropriate levels of abstractions to allow the simplification and convenient reuse of proof steps across many variations of the voting scheme. The resulting framework enables machine-checked security proofs for several hundred variants of Helios and should serve as a stepping stone for the analysis of further variations of the scheme. In addition, we highlight some of the lessons learned regarding the gap between pen-and-paper and machine-checked proofs, and report on the experience with formalizing the security of protocols at this scale.

Blockchain Technology || The Future ? ||
Blockchain Technology || The Future || Blockchain technology || The Future || 1. Many people know it as the technology behind Bitcoin, but blockchain’s potential uses extend far beyond digital currencies. So what exactly is blockchain, and why are Wall Street and Silicon Valley so excited about it? 2. What is blockchain? Currently, most people use a trusted middleman such as a bank to make a transaction. But blockchain allows consumers and suppliers to connect directly. 3. Continue… Using cryptography to keep exchanges secure, blockchain provides a decentralized database, or “digital ledger”, of transactions that everyone on the network can see. This network is essentially a chain of computers that must all approve an exchange before it can be verified and recorded. 4. In the case of Bitcoin, blockchain stores the details of every transaction of the digital currency, and the technology stops the same Bitcoin being spent more than once. How does it work in practice? 5. 6 How does it work in practice? 6. Why is it so revolutionary? Work for almost every type of transaction involving value, including money, goods and property. Its potential uses are almost limitless: from collecting taxes to send money back to family in countries where banking is difficult. Help to reduce fraud because every transaction would be recorded and distributed on a public ledger for anyone to see. 7. Where can it be used? • Banks, notary offices, Bitcoin ATM's, Voting, etc. • Places where there is need of the high security. • Irrevocable, transaction, contract, or any other digital data stored on it. 8. Why are banks interested? Banks can use it for money transfers, record keeping and other back- end functions. Replicates the paper- intensive international trade finance process as an electronic decentralized ledger, A single source of information. Track documentation and authenticate ownership of assets digitally. 9. Is it safe? USP : Execute a transaction without any intermediary. Financial institutions to execute and verify transactions discretely without any human intervention. The electronic ledger of transactions is continuously maintained and verified in 'blocks' of records. With the help of cryptography, the tamper-proof ledger is shared between parties on computer servers. Bring down the costs and reduce inefficiencies in the financial sector. 10. What Is a Blockchain Wallet? Wallet technology could be used for any system using a blockchain. A wallet is a piece of software or hardware that “holds” your cryptocurrency. Place that your public and private keys are stored. The wallet is the only record of your keys. So if you lose it, you’ll no longer have access to your cryptocurrency. 11.

The History Of Blockchain Explained
To find out more about how blockchain works, check out our free guide: https://www.cryptomaniaks.com/learn/the-blockchain/get-started We’ll start at the very beginning by understanding the history of blockchain. By using math and cryptography, Blockchain is challenging the status quo in a radical way. Will governments and financial institutions embrace it? ●▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬● 🏠 Website: www.cryptomaniaks.com 👨‍🎓Free Courses on Bitcoin, Blockchain, Cryptocurrency Investment ... https://www.cryptomaniaks.com/learn 🤑Step-by-Step Guide to Get Started Investing in Cryptocurrency: https://cryptomaniaks.com/ultimate-beginners-guide-invest-cryptocurrency/course/start-investing 👤Facebook Page: http://bit.ly/PageManiaks ●▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬● 💰Buy Bitcoin/Ethereum On CoinBase: https://rebrand.ly/coinbase-CryptoManiaks 👻Trade Cryptos On Binance: https://rebrand.ly/binance-CryptoManiaks 🔒Secure your Cryptos with Ledger Nano S: https://rebrand.ly/ledger-CryptoManiaksManiaks ●▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬● The very first blockchain in the world was Bitcoin. An anonymous person or group known as Satoshi Nakamoto published a document in an online cryptography forum in November 2008 and revealed the first details of how it would work, describing it as a “peer-to-peer electronic cash system”. The whitepaper is available today at bitcoin.org/bitcoin.pdf. It allows any 2 people to pseudonymously send money to each other no matter where they are in the world. It is a borderless currency. The main benefit of Bitcoin is that it does not require any centralized authority or institution to operate. This is in contrast to today’s centralized financial systems that depend on the existence of a central bank or government to mint money. If for any reason the central authority were to shutdown, the money would become worthless. In a decentralized system like Bitcoin, there is no central authority and the system can continue to operate as long as there are members in its peer-to-peer network. The goal of the whitepaper was to describe how the different parts of the Bitcoin protocol would operate and be kept secure. A new type of database, called a blockchain, would keep track of a single history of all Bitcoin transactions and it would be maintained by everyone in the network. The database would be publicly available for anyone to view and inspect, and anyone can download a copy of the same database. This provides data redundancy and makes sure the data is never lost, but also provides a way for anyone to verify the transactions in the database themselves. A block in the database just stores a sequence of transactions, and a sequence of blocks is called a blockchain. Each block is identified by an incrementing number and a unique Sha-256 hash. The hash for a block is calculated using the transactions inside it, as well as the previous block’s hash, which forms a chain of hashes. The data in the blocks is secured using a cryptographic algorithm called proof-of-work, which also keeps all members of the network and the database in sync to prevent double-spending. In this context, preventing double-spending means preventing anyone from spending money they dont have. Proof-of-work is used to generate new blocks for the database, also known as mining, and the reward for mining a new block is given to the miner by creating new Bitcoins in the system. This is the only way new Bitcoins can be created. Anyone on the network can be a miner and a new block is mined roughly every 10 minutes, which includes the latest set of verified transactions. The first release for Bitcoin was version 0.1 written in C++ by Satoshi and published on SourceForge in January 2009 under the open-source MIT license. Anyone could download the source code and run it to join the network, also known as becoming a node in the network. This is the original version 0.1 source code written by Satoshi. We can see the hard-coded genesis block, which is the very first block in the chain. The hash for the block can be verified by using any Bitcoin blockchain explorer. Let’s copy and paste this hash into the blockchain explorer available at blockchain.info. We can see that this hash is for block number 0, and that it has only one transaction in it which is the mining reward, and the reward amount of 50 Bitcoin was given to this Bitcoin address. We can also see this 50 Bitcoin reward for the genesis block in the original source code. The genesis block is a special case needed to start the blockchain and is the only block that is hard-coded, whereas every subsequent block is calculated using proof-of-work. Satoshi’s motivation for creating Bitcoin is revealed in the piece of data he included in the genesis block: a newspaper ...

Quantum Key Distribution: Provably Secure Encryption
Hackers steal data constantly, so protecting it is an ongoing challenge. Today's information encryption technology has been compromised and will be obsolete in just a few years. Quantum Key Distribution (QKD) technology can be proven by the laws of physics to help secure the sensitive data we deliver—today and into the future.

CERIAS Security: An Anonymous Fair-Exchange E-Commerce Protocol 1/5
Clip 1/5 Speaker: Indrakshi Ray · Colorado State University Many business transactions over the Internet involve the exchange of digital products between two parties -- electronic mails, digital audio and video, electronic contract signing and digital signatures, to name a few. Often these transactions occur between players that do not always have identifiable place of doing business and hence do not trust each other. Consequently, there exists ample scope for any of the parties involved, to misbehave and gain advantage over the other party. To overcome this problem researchers have proposed protocols that ensure fairness, that is, no party can gain an advantage even if the party misbehaves. Most works in this area focus on gathering evidence during the protocol execution that is used later, in case of a dispute. The actual handling of the dispute is done manually, after the protocol execution, and is outside the scope of the protocol. However, in an electronic commerce environment, where the merchants and customers may disappear quickly, such "after-the-fact" protection may be inadequate. In this work we propose an e-commerce protocol for trading digital products over the Internet. The novel features of our protocol include: (1) ensuring fair exchange, (2) not requiring manual dispute resolution in case of unfair behavior by any party, (3) assuring each party that the item he is about to receive is indeed the correct one, (4) not requiring the active involvement of a trusted third party unless a problem occurs, and (5) ensuring anonymity for the customer.
