Google Cloud KMS Adds Quantum-Safe Digital Signatures to Defend Against Future Threats

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)
