Accelerating DNSSEC authoritative zone signing and denial-of-existence proofs for high-velocity domain registrars.
Signing large top-level domain (TLD) or enterprise DNS zones requires computing hundreds of thousands of digital signatures every few hours as records expire. NetworkHSM utilizes parallelized asymmetric cryptographic coprocessors that sign complete zones in seconds without service interruption.
The authoritative Key-Signing Key (KSK) is held permanently within physical tamper-proof silicon, while automated Zone-Signing Keys (ZSK) are rotated in software under hardware envelope supervision.
