Cloud Security / Encryption
  Google Cloud has announced quantum-safe digital signatures in Google Cloud Key Management Service ( Cloud KMS ) for software-based keys as a way to bulletproof encryption systems against the threat posed by cryptographically-relevant quantum computers.  The feature, currently in preview, coexists with the National Institute of Standards and Technology's (NIST) post-quantum cryptography (PQC) standards, the final versions of which were formalized  in August 2024.   "Our Cloud KMS PQC roadmap includes support for the NIST post-quantum cryptography standards (FIPS 203, FIPS 204, FIPS 205, and future standards), in both software (Cloud KMS) and hardware (Cloud HSM)," the company's cloud division noted .  "This can help customers perform quantum-safe key import and key exchange, encryption and decryption operations, and digital signature creation."  The tech giant said its underlying software implementations of these standards – FIPS 203 (aka ML-KEM), FIPS 204 ...
