Post-Quantum Cryptography (PQC)

  • PQC signatures for software images with off-box verification (ACX Series, EX Series, MX Series, QFX Series, and SRX Series)—Use post-quantum cryptography (PQC) signatures to ensure software images remain unaltered, protecting integrity and guarding against quantum threats. The images comply with algorithms recommended by Commercial National Security Algorithm 2.0 (CNSA 2.0):

    • ML-DSA-87 PQC algorithm for digital signatures

    • SHA-512 for hashing

    For off-box verification, request the PQC signature from the support portal. Confirm the image’s SHA-512 hash, retrieve the public key from the certificate, and validate the signature with your chosen verifier. PQC signatures provide additional security beyond existing legacy signatures.
