Cloudflare accelerates post-quantum security to 2029

Cloudflare is advancing its timeline for full post-quantum security, now targeting 2029 for complete protection, including authentication. This acceleration is driven by recent breakthroughs in quantum computing, notably Google's improved quantum algorithm for breaking elliptic curve cryptography and Oratomic's resource estimates for breaking RSA-2048 and P-256. These developments suggest the threat of 'Q-Day,' when quantum computers can compromise current encryption, is closer than previously anticipated, potentially as early as 2029 or 2030. Cloudflare, which already offers post-quantum encryption for most traffic, emphasizes the urgent need to upgrade authentication protocols to counter these emerging quantum threats.
