"Google Chrome to Shield Encryption Keys From Promised Quantum Computers"

Google has deployed a hybrid Key Encapsulation Mechanism (KEM) to protect symmetric encryption secret sharing while establishing secure Transport Layer Security (TLS) network connections. Devon O'Brien, the technical program manager for Chrome security, explained that starting with Chrome 116, Google's browser will support X25519Kyber768. The term is a combination of X25519, an elliptic curve algorithm currently used in the key agreement process for establishing a secure TLS connection, and Kyber-768, a quantum-resistant KEM that received NIST's approval for post-quantum cryptography last year. A KEM is a method for establishing a shared secret value between two parties in order for them to communicate in confidence using symmetric key encryption. It is a precursor to the secure exchange of information over a network. Google is deploying a hybrid version of the two algorithms in Chrome so that the web giant, users of its technology, and other network providers such as Cloudflare can test quantum-resistant algorithms while maintaining current security measures. This article continues to discuss Google's effort to protect encryption keys from quantum computers.
