Fixing Encryption Isn't Enough. Quantum Developments Put Focus on Authentication
Google research has revised the quantum threat timeline, finding elliptic curve cryptography could be broken with as few as 1,200 logical qubits, prompting both Google and Cloudflare to move their Q-day estimates to 2029. The industry's focus on encrypting data in transit has obscured a more urgent risk: authentication and certificates, where a single compromised quantum-vulnerable key enables full system access and turns software update pipelines into RCE vectors. Enterprises are advised to begin crypto-agility inventories now and treat PQC migration as a dedicated workstream outside normal security operations, given that large-scale migrations can take years.
