Google Cloud has introduced quantum-safe digital signatures to its Cloud Key Management Service (Cloud KMS), making them available in preview.

The tech giant says this initiative aligns with the National Institute of Standards and Technology's (NIST) post-quantum cryptography (PQC) standards, addressing future risks of quantum computing breaking classic encryption schemes.
