Signal recently announced the introduction of another layer of post-quantum cryptography to their protocol, this time in their ratcheting mechanism. Let's take a look!

In March 2024, SandboxAQ proposed a CTF around Post-Quantum Cryptography (and more specifically Kyber's key exchange) for the RWPQC workshop. Here is our write-up of the solutions to the challenges.

Post-quantum cryptography is an active field of research, especially since the NIST Call for Submissions in 2016 to design new standards for asymmetric key cryptography. The aim of post-quantum cryptography is to mitigate the risk of a large-scale quantum computer which may break all the asymmetric cryptography that is deployed today. This blogpost will present the activity state of the post-quantum cryptography field and sketch the challenges for the deployment of post-quantum safe standards for the industry, both in term of internal infrastructures and security products.
