| description | Aspects related to the secure transfer and use of secret material are described. In one embodiment, an encrypted secret key and encrypted revocation data are imported into a trusted execution environment and decrypted with private provider and vendor keys. In this manner, a provider of cryptographic processes is not exposed to the secret key or revocation data of a customer, as the secret key and revocation data are decrypted and stored within the trusted execution environment but not accessed in an unencrypted form. In turn, the provider can receive various instructions to perform cryptographic operations on behalf of the customer. Based on the outcome of a revocation check using the revocation data, the instructions can be performed by the trusted execution environment. |
