Future-proofing data integrity: Quantum-safe digital signatures in Cloud KMS
Google Cloud has announced the general availability of quantum-safe digital signatures (ML-DSA, SLH-DSA) and post-quantum key encapsulation (ML-KEM) in Cloud KMS. These additions aim to protect long-term data integrity against potential threats from cryptographically relevant quantum computers.
Why it matters
Organizations can protect their sensitive data from future quantum attacks and meet government regulatory timelines for cryptographic transitions. The new variants also allow users to sign large files securely without encountering processing delays.
The details
- Cloud KMS supports ML-DSA and SLH-DSA algorithms across different NIST security levels.
- External-µ variants enable efficient signing of large data payloads through external hashing.
- The updates assist organizations in meeting U.S. government quantum-safe transition timelines.
