Google announced a roadmap to implement NIST post-quantum cryptography standards in Cloud KMS, providing preview support for software-based customer-managed encryption keys (CMEKs) that use lattice-based (FIPS 204) and stateless hash-based (FIPS 205) digital signatures, with FIPS 203 (KEM) support planned later. The company is releasing open-source implementations in BoringCrypto and Tink, working with HSM and EKM partners, and deploying PQC internally across services to enable customer migration and performance testing; the article is informational and not a report of a security incident.
