Future-proofing data integrity: Quantum-safe digital signatures in Cloud KMS
With cryptographically relevant quantum computers (CRQC) on the horizon, transitioning to quantum-safe digital signatures is critical to safeguarding long-term data integrity and authenticity. Organizations are steadily recognizing this urgency.
For example, the U.S. government announced an update to the timelines by which departments and agencies must transition to quantum safe digital signatures. To help with the transition, we are announcing the general availability of our quantum-safe digital signatures (ML-DSA, SLH-DSA) and post-quantum key encapsulation (ML-KEM) in Google Cloud Key Management Service (Cloud KMS).
The immediate challenge for your organization is functional: You need to sign massive data payloads without encountering the bandwidth and processing issues inherent with post-quantum cryptography (PQC). To proactively address these emerging threats and help you support compliance with regulatory obligations, you can use the suite of PQC digital signature algorithms available in Cloud KMS, which includes ML-DSA (FIPS 204) and SLH-DSA (...
