Google Cloud has launched quantum-safe digital signatures in its Cloud KMS, aiming to protect against quantum computer threats. This move coexists with NIST's PQC guidelines, ensuring a consistent approach to post-quantum cryptography. Organizations using software-based keys must adapt to this change, potentially updating their encryption systems. A direct comparison of Google's solution with other PQC methods is necessary to understand its strengths and weaknesses.
