Google Cloud's Roadmap to a Quantum-Safe Infrastructure
🔒 Google Cloud has been migrating its infrastructure toward post-quantum cryptography for nearly a decade to mitigate Store Now, Decrypt Later (SNDL) risks. The company has deployed the standards-based ML-KEM (FIPS 203) for key exchange across internal traffic and the Google Cloud networking stack, and introduced ML-KEM capabilities in Cloud KMS (preview) for key generation, encapsulation, and decapsulation. It also added native support for ML-DSA and SLH-DSA in Cloud KMS to protect long-lived digital signatures, and is phasing quantum-safe certificate support into Certificate Authority Service to enable future PQC-ready PKI. Administrators will receive tooling to opt in, audit cryptographic assets, and manage transitions to hybrid or pure PQC deployments as standards mature.
