Enhanced Key Takeaways
- •Cloudflare is prioritizing the deployment of Kyber (ML-KEM) and Dilithium (ML-DSA) algorithms, which were recently standardized by NIST to provide resistance against Shor's algorithm.
- •The 2029 target is specifically aligned with the 'Q-Day' threat model, where cryptographically relevant quantum computers (CRQCs) are projected to break current RSA and ECC encryption standards.
- •Cloudflare's strategy involves a hybrid key exchange approach, combining classical ECDH with post-quantum algorithms to ensure security against both current and future threats during the transition period.
