A few weeks ago I started building a post-quantum encryption library. One of the protocols, which I called BLUE, is supposed to give built-in plausible deniability. I've been thinking about deniability for a while. I've seen VeraCrypt and it's great, …
Hello everyone! In the last few weeks, I was trying to find a good ECDSA explanation to share with a colleague and I was surprised to find no post with an actual visual explanation for the algorithm. So that's why …
Revaulter is an app that I've been using for 6 years to unwrap keys for unlocking my servers' HDDs and for performing backups. A CLI creates requests, then a user can sign into a web page and use web-based crypto …
In the 2010s, there was considerable interest in and VC funding for quantum algorithms for machine learning, based largely upon the Kerenidis and Prakash quantum recommendation system. [Ewin Tang undergrad project](https://arxiv.org/abs/1807.04271) de-quantized this algorithm, effectively killing the field of quantum …
I noticed a possible connection between the standard Walsh conditions for Boolean functions and the spectrum of one finite graph. In Boolean-function cryptography, balancedness, correlation immunity, and resilience are usually checked through the vanishing of low-weight Walsh coefficients. So the …
Post-quantum encrypted IRC with zero-knowledge identity verification now running entirely in Rust. No Python secrets. Months ago I posted this project here. The main criticism was that SMP exponents were Python int objects with no deterministic zeroization. That's fixed. The …
[Copy Fail](https://xint.io/blog/copy-fail-linux-distributions) allows privilege escalation on Linux distributions. The root cause is due to an AEAD encryption bug, writing 4 bytes beyond the AEAD tag. I wish I could say more but I have never read the Linux kernel so …
