- Google Cloud now offers PQC algorithms for digital signatures
- This decision is part of the Google Cloud Quantum-Safe roadmap
- The functionality is available in preview now, with more PQC changes to come
Google Cloud has taken an additional step to secure its platform from the threat posed by quantum computer science to public key cryptography by announcing the availability of digital signatures in terms of quantum in the overview in the management service Google Cloud keys.
Theoretically, quantum computers will be able to break most modern encryption algorithms in a few hours, but the viability of such a system is still a decade by most expert estimates.
However, this presents threats today, cybercriminals today flying vulnerable encrypted data in order to decrypt it when the relevant quantum computers in relevant relevance. This required the development of post-health cryptography (PQC) to secure data against the attacks of “harvest-decrypt-later”.
Secure the future of digital signatures
Digital signatures in quantum safety are only a Google Cloud roadmap stage to a fully PQC platform.
For digital signatures in particular, Quantum brings the threat of counterfeiting and falsification, with Google Cloud stressing that working to resolve these threats will now help create a more resilient infrastructure and inspire other platforms to do the same.
Google Cloud has also revealed in the announcement that to help apply the transparency and auditability of the code, the quantum -related software implementations will be available in the context of open source cryptographic libraries from Google Boringcrypto and Tink.
This update of digital signatures specifically implements PQC ML-DSA-65 and SLH-DSA-SHA2-128S algorithms in accordance with NIST standards. Google Cloud will also implement new PQC algorithms and techniques in its hardware safety modules (HSM).
Google Cloud customers will be able to use the latest PQC algorithms in Cloud KMS and provide comments on their implementation, and suggestions on other specific cryptographic requirements. Essentially, the use of the latest Cloud KMS algorithms acts as a test bench for the construction and widening of PQC availability on the Google Cloud platform.
