Cloudflare Sets 2029 Deadline for Quantum-Resistant Platform
Cloudflare has announced that its entire platform will be quantum-resistant by 2029. This comes after Google's announcement last month to also achieve this goal by 2029. Research from Google and IBM suggests 'Q-Day', when a quantum computer can crack current cryptography, could arrive as early as 2032.
The company is focusing first on post-quantum authentication, warning that compromised authentication keys could allow attackers to impersonate servers or gain unauthorized access. Sharon Goldberg, Cloudflare's senior director of product management, said the authentication upgrade is harder than encryption.
'With post-quantum encryption upgrades to TLS, we only need to upgrade the TLS client and the TLS server,' she said.
The rollout plan starts with origin connections in mid-2026, expands to visitor connections in mid-2027, and reaches full deployment by 2029. Over 65% of human traffic to its network already uses post-quantum encryption.
