Google Sets Timeline for Post-Quantum Cryptography Migration

Google has announced an ambitious timeline targeting 2029 for its full migration to post-quantum cryptography (PQC). This timeline is influenced by advancements in quantum computing hardware, quantum error correction, and estimates for quantum factoring resources. The company has shifted its threat model to prioritize PQC migration for authentication services due to 'store-now-decrypt-later' attacks, where adversaries harvest current encrypted data for future decryption by powerful quantum computers. As a tangible step, Google is integrating PQC digital signature protection using ML-DSA (a NIST-standardized algorithm) into Android 17. Google stated its responsibility is to lead by example to accelerate this digital transition across the industry. This announcement coincides with the Ethereum Foundation also targeting 2029 for L1 protocol upgrades, although some experts still believe the quantum threat is at least a decade away.
