Google Moves Q-Day Estimate to 2029: RSA Encryption May Need 20x Fewer Quantum Resources Than Thought

Ars Technica·high signal

Google published research finding that cracking RSA encryption may require 20 times fewer quantum resources than previously estimated, compressing the 'Q-Day' timeline from 2035+ to 2029. Google plans to integrate post-quantum cryptography into Android 17 by June, accelerating the NSA's original 2031 implementation timeline. The company warns adversaries are already conducting 'store now, decrypt later' attacks, collecting encrypted data for future quantum decryption.
