NIST’s pleasant post-quantum surprise

The US National Institute of Standards and Technology (NIST) has announced the post-quantum cryptography it will standardize, with Kyber chosen for key agreement and three signature schemes - Dilithium, Falcon, and SPHINCS+. This is a significant step towards securing the internet against potential quantum computer threats in the future. The selected algorithms offer good performance characteristics and security levels, making them suitable for practical deployment on the internet. Cloudflare has been working on implementing post-quantum cryptography and contributing to standards, and they are excited about this development. They also provide guidance on how developers can start experimenting with these new algorithms in their software stacks.
