Abstract
A device and corresponding method control use of keys in key slots of a Hardware Security Module (HSM) key vault. The device comprises the HSM key vault and a HSM. The HSM stores a key for use in a cryptographic operation and slot key-information of the key in a key slot of the key slots. The slot key-information includes a key type of the key. The key slots are available for storing the key irrespective of the key type. The key type is associated with the cryptographic operation. The HSM controls use of the key based on a decision to grant or deny a request that includes request key-information and a slot identifier of the key slot. The HSM locates the key slot via the slot identifier, makes the decision based on the request key-information and slot key-information, and outputs a response to the request that indicates the decision made.
