After Years of Controversy, the EU’s Chat Control Nears Its Final Hurdle: What to Know
Resource to learn about TLS optimization
I’m trying to learn how to optimize TLS performance in real systems, especially in service meshes (like Istio or Linkerd) and load balancers (like Nginx or HAProxy). What practical steps, tools, or metrics should I focus on when tuning TLS handshakes, cipher suites, session resumption, hardware acceleration, or certificate-chain details? …
Introducing constant-time support for LLVM to protect cryptographic code
Black is white and white is not black
Great, you’ve just read a genuine contradiction. In classical logic, once your assumptions contain something of the form “P and not P”, the system explodes: from that point on you can prove \*\*anything\*\* you like. (yes, we assume "is" is a symmetric equality) Want to “prove” that God does not …
A branchless modulo alternative with ~6x speedup for polynomial additions on ARM (REIST Division)
While working on modular arithmetic for lattice based cryptography, I experimented with a generalized form of integer division that uses a symmetric remainder interval instead of the classical non-negative one. The goal was not to change semantics in cryptographic algorithms, but to simplify the reduction step that dominates polynomial additions. …
Is it possible to lift Elliptic curves over finite fields to Elliptic curve over dual numbers?
This is for the discrete logarithm. I don t even need for the lifted points to be dependent. Of course, this is possible to anomalous curves, but what about secure curves?
WebRTC and Onion Routing Question
I wanted to investigate about onion routing when using WebRTC. Im using [PeerJS](https://peerjs.com/) in my app. It allows peers to use any crypto-random string to connect to the peerjs-server (the connection broker). To improve NAT traversal, im using [metered.ca](http://metered.ca/) TURN servers, which also helps to reduce IP leaking, you can …
