Google adds PQC to Chrome

· One min read

Google announced plans to add support for quantum-resistant encryption algorithms in its Chrome browser, starting with version 116. The chosen algorithm, X25519Kyber768, combines the output of X25519, an elliptic curve algorithm widely used for key agreement in TLS, and Kyber-768 to create a strong session key to encrypt TLS connections, providing roughly the security equivalent of AES-192.

While the equivalency of AES-192 may not provide a security improvement for many adopters today, the general inclusion of PQC algorithms is a welcomed improvement in what will be a multi-year adoption journey across the industry to protect user network traffic against future quantum cryptanalysis.
