Solving LPN Using Large Covering Codes
Since quantum computers are expected to break most of the cryptographic schemes we rely on today, we need to look at alternatives. Learning Parity with Noise (LPN) is mathematical …
Rephrasing TLS key exchange in terms of KEMs
In the RFC for TLS 1.3 (RFC8446) especially, the key exchange is defined in terms of (EC)DH key shares being exchanged. This limits us to algorithms which support non-interactive …
Using (post-quantum) KEMs in TLS 1.3
The new TLS 1.3 standard \[1\] does not yet provide any support for post-quantum algorithms. In this blog post we’ll be talking about how we could negotiate a post-quantum key …
Solving LPN using Large Covering Codes
Learning Parity with Noise (LPN) is a computational problem that we can use for cryptographic algorithms. It is suspected that LPN can not be solved (much) more efficiently on a …
Latincrypt paper!
I’m going to Cuba as my submission to Latincrypt 2017 was accepted! The paper is called Energy-efficient ARM64 Cluster with Cryptanalytic Applications: 80 cores that do not cost …
Securing OpenSSH
You can set up SSH to prefer Elliptic Curve cryptography over RSA, and use modern key exchange algorithms without exposing yourself to Logjam-style attacks. It’s also good to get …
Implementing CAESAR candidate Prøst on ARM11
Prøst was a contestant in the CAESAR competition for Authenticated Encryption. I optimised Prøst for the ARM11 microprocessor architecture. By trying to find a provably minimal …
