Google has announced the integration of encryption algorithms resistant to attacks using quantum computing into its Chrome browser. We’re talking about introducing a Hybrid Key Encapsulation (KEM) mechanism to protect the process of establishing a secure TLS connection. The innovation will be implemented in Chrome 116, the stable version of which will be available to users from August 15th.
The browser will support X25519Kyber768 encryption, which combines the classic X25519 algorithm and Kyber-768, a quantum-resistant key encapsulation mechanism approved last year by the US National Institute of Standards and Technology (NIST) for use in post-quantum cryptography became. Google is introducing a new hybrid mechanism for Chrome to allow big internet companies like Cloudflare to test quantum-resistant algorithms while maintaining the current level of protection.
Work is underway to develop new mechanisms due to fears that quantum computers could destroy some of the encryption algorithms currently in use. These concerns prompted NIST back in 2016 to urge developers to create algorithms resistant to quantum computing.
According to experts, in 5, 10 or even 50 years, quantum computers capable of cracking modern cryptographic algorithms could appear on the market. Nevertheless, the development of stable algorithms is an important task today. This is because some algorithms are vulnerable to temporary attacks, where data is collected and stored until cryptanalysis is more advanced.
