Abstract
A method for a policy-based association of a hardware security module to a secure guest is disclosed. The method comprises maintaining a binding between a secure guest and an HSM. Thereby, the binding enables the trusted guest to send only non-sensitive request to the HSM. The method comprises further maintaining, for a secure guest, a pair of a secret and a secret name, submitting a query to the bound HSM for obtaining HSM configuration data, and upon determining that the obtained HSM configuration data match a rule available to the secure guest, wherein the rule associates the HSM to a secret name, requesting to associate the secret from the pair of secret and the secret name to the bound HSM, thereby triggering that the trusted firmware allows the secure guest to submit a sensitive crypto-request to the bound and associated HSM.
