HSM Services
Hardware security modules and the key management around them — the cryptographic foundation that card, PIN and token operations depend on.
How a request moves through it
Request
An application asks for a cryptographic operation.
Authenticate
The HSM confirms the caller and its permissions.
Execute
The operation runs inside the tamper-resistant boundary.
Respond
Only the result leaves the HSM; keys never do.
Log
The operation is recorded for audit.
What goes in, and what comes out
- A PIN block
What happens: Translated between keys inside the HSM
Comes out: A PIN block under the destination key
- A card authorisation
What happens: Cryptogram verified against the issuer key
Comes out: A verified or rejected authorisation
- A key ceremony
What happens: Keys generated or loaded under dual control
Comes out: Keys in service and a ceremony record
Controls built into every step
Safeguards we design in from the start rather than add for an audit.
- Dual control and split knowledge for key management
- Keys never exposed outside the HSM boundary
- Key lifecycle documented from generation to destruction
Questions buyers ask
It depends on the systems it connects to. A scoping session gives a realistic plan for your estate.
