Qualified Signature Creation Devices & Sole Control Compliance
Engineering server-side qualified signature creation devices compliant with eIDAS, EN 419 241-1, and EN 419 241-2 standards.
Signature Activation Module (SAM) Architecture
SignHSM incorporates a certified Signature Activation Module running inside the cryptographic boundary, verifying signed authorization tokens from identity providers before releasing private signing keys for a single, non-replayable operation.
High-Density Key Storage & HSM Virtualization
By leveraging master wrapping keys protected by hardware TRNGs and physical tamper shields, SignHSM securely manages millions of active user signing keys stored in external databases with sub-millisecond retrieval and decryption.
- Sole Control Assurance: Cryptographic Signature Activation Data (SAD) verification ensuring only the user can authorize signing.
- Hardware Multi-Tenancy: Secure spatial partitioning allowing millions of individual user signing keys within a single HSM cluster.
- Legal Equivalence: Guaranteeing unconditional legal parity with handwritten signatures across all EU Member States.
- Audit Trail Immutability: Cryptographically chaining all signing events to tamper-proof internal audit registers.
