Proposed New OpenPGP Cipher Block Modes Could Cause an Interoperability Disaster

I made a cryptographically secure RNG library

I have been working on this for almost two semesters, and this has been my most fun and ambitious project so far: [https://github.com/vibhav950/Xrand](https://github.com/vibhav950/Xrand) * The RNG extracts entropy from several system processes and even user interaction. * I have also implemented all three NIST-approved DRBGs for fast pseudorandom data generation. …

Secret key sampling?

Hey gang, I am working on a lattice system based on the ISIS problem. ChatGPT keeps thinking this is a terrorist form of cryptography, but it's just inhomogeneous short integer solution. With that out the way, I'm wondering about short secret generation. I've become partial to using a Gaussian distribution …

Encrypted DNA Testing Using Fully Homomorphic Encryption

DNA testing platforms analyze your genetic data in the clear, leaving it vulnerable to hacks. With Fully Homomorphic Encryption (FHE), they could perform this analysis on encrypted data, ensuring your sensitive information remains safe, even during processing, allowing to get the knowledge without the risks. In this demo, we show …

Trivial question on metadata analysis

Obviously modern sym ciphers like AES and ChaCha are super strong. But wondering about best practice with regard to theoretical statistical analysis about message lengths, times sent etc. is there best practice on this?

Are current cryptography methods vulnerable in any way?

Hi, Im working on a school project about vulnerabilities of current cryptography methods and its implementation in critical infrastructure. I have already done some research, but to be honest there is not much about it, it basicaly boils down to side-channel attacks (this is more of a implementation problem than …

Full beginner here , no knowledge of cryptography whatsoever apart from simple ciphers , what books would u recommend ?

Any books regarding history of cryptography or just some books to get into cryptography would be great
