Google accelerates its post-quantum cryptography migration timeline
Google published a timeline targeting post-quantum cryptography migration by 2029 and emphasized authentication and digital signatures alongside protection from harvest-now-decrypt-later attacks. The roadmap prioritizes systems with long-lived keys, long data-retention periods, or difficult dependency chains.
Why it matters: Quantum risk is turning into an immediate cryptographic-inventory and migration problem even though a cryptographically relevant quantum computer has not been demonstrated.
