Automated DNSSEC Zone Signing & NSEC3 Cryptographic Proofs

Accelerating DNSSEC authoritative zone signing and denial-of-existence proofs for high-velocity domain registrars.

Overcoming DNSSEC Computational Bottlenecks

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.

Hardware Key-Signing Key (KSK) Protection

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.

Line-Rate Zone Signing: Signing millions of DNS Resource Records (RRsets) with ECDSA P-256 and Ed25519.
Automated Key-Signing Key (KSK) Rollover: Automated parent-zone DS record updates via CDS / CDNSKEY.
Hardware NSEC3 Hash Acceleration: Computing salted iterated SHA-1/SHA-256 hashes to prevent zone enumeration.
Defense Against DNS Cache Poisoning: Delivering cryptographically authenticated answers that resolver caches verify.
