Encrypt message with python
 
08:00
This video is sponsor by CODE !We code for the future!. In this video i show how to encrypt a message with python. We used a program called Reverse Cipher. This program is not too complex to write. I want to remind you that Reverse only run with python 3.3 you can go and download it at python.org Now Let me give you some tips of how this program works. You will see message = this is where you write the message in stort terms. Len() is a statement the store the value in a variable i. While i this is called while loop or while statement tells python to do his first check to see what is the condition. If you have any question or need more information contact us at [email protected]

Defeat 2FA token because of bad randomness - rhme2 Twistword (Misc 400)
 
10:25
Generating random numbers on computers is not easy. And while the intended solution was really hard, the challenge had a problem with the random number generation, which allowed me to solve it. Clarification from Andres Moreno (riscure) on the challenge: "The "official" challenge solution involved reading the tiny Mersenne twister (tinyMT) paper, writing some equations, and using a solver. The tinyMT is tricky to initialize. Giving a proper seed is not enough. You need to provide initial state matrices with certain properties (there is a generator for this). The challenge used improper initialized matrices (zeros) that reduced the PRNG period. During tests, we found that ~12hr were needed to solve the challenge (solver time only), but we did not test the amount of entropy reduction by improper state initialization. Fortunately, the problem was not in the PRNG." -=[ 🔴 Stuff I use ]=- → Microphone:* https://amzn.to/2LW6ldx → Graphics tablet:* https://amzn.to/2C8djYj → Camera#1 for streaming:* https://amzn.to/2SJ66VM → Lens for streaming:* https://amzn.to/2CdG31I → Connect Camera#1 to PC:* https://amzn.to/2VDRhWj → Camera#2 for electronics:* https://amzn.to/2LWxehv → Lens for macro shots:* https://amzn.to/2C5tXrw → Keyboard:* https://amzn.to/2LZgCFD → Headphones:* https://amzn.to/2M2KhxW -=[ ❤️ Support ]=- → per Video: https://www.patreon.com/join/liveoverflow → per Month: https://www.youtube.com/channel/UClcE-kVhqyiHCcjYwcpfj9w/join -=[ 🐕 Social ]=- → Twitter: https://twitter.com/LiveOverflow/ → Website: https://liveoverflow.com/ → Subreddit: https://www.reddit.com/r/LiveOverflow/ → Facebook: https://www.facebook.com/LiveOverflow/ -=[ 📄 P.S. ]=- All links with "*" are affiliate links.

Post-Quantum Zero-Knowledge and Signatures from Symmetric-Key
 
33:34
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/

Crypto Defenses for Real-World System Threats - Kenn White - Ann Arbor
 
01:36:58
Modern encryption techniques provide several important security properties, well known to most practitioners. Or are they? What are in fact the guarantees of, say, HTTPS TLS cipher suites using authenticated encryption, IPSec vs. SSL VPNs, Property Preserving Encryption, or token vaults? We live in an era of embedded Hardware Security Modules that cost less than $1 in volume, and countless options now exist for encrypting streaming network data, files, volumes, and even entire databases. Let's take a deep dive into the edge of developed practice to discuss real-world threat scenarios to public cloud and IoT data, and look closely at how we can address specific technical risks with our current encryption toolkits. Advanced math not required. Bio: Kenneth White is a security researcher whose work focuses on networks and global systems. He is co-director of the Open Crypto Audit Project (OCAP), currently managing a large-scale audit of OpenSSL on behalf of the Linux Foundation's Core Infrastructure Initiative. Previously, White was Principal Scientist at Washington DC-based Social & Scientific Systems where he led the engineering team that designed and ran global operations and security for the largest clinical trial network in the world, with research centers in over 100 countries. White co-founded CBX Group which provides security services to major organizations including World Health, UNICEF, Doctors without Borders, the US State Department, and BAO Systems. Together with Matthew Green, White co-founded the TrueCrypt audit project, a community-driven initiative to conduct the first comprehensive cryptanalysis and public security audit of the widely used TrueCrypt encryption software. White holds a Masters from Harvard and is a PhD candidate in neuroscience and cognitive science, with applied research in real-time classification and machine learning. His work on network security and forensics and been cited by media including the Wall Street Journal, Forbes, Reuters, Wired and Nature. White is a technical reviewer for the Software Engineering Institute, and publishes and speaks frequently on computational modeling, security engineering, and trust. He tweets @kennwhite.

5 - Casser le cryptage RSA - Comprendre comment marche le SSL
 
27:50
Après vous avoir montrer comment se déroule le cryptage RSA et les opérations et processus mathématiques qui le compose, je vous propose désormais qu'on voit comment le casser avec l'algorithme de Shor. En effet, tout repose sur la multiplication de deux nombres premiers très importants. Si on était capable de factoriser N alors on pourrait tout retrouver. L'algorithme de Shor prévoit justement cela en 7 étapes.
