Abstract: An apparatus can include an interface coupled to processing circuitry and cryptographic circuitry coupled to the interface. The cryptographic circuitry can receive a request from the processing circuitry over the interface to perform a cryptographic operation using a remote hardware security module (HSM) key component. The cryptographic circuitry can further transmit a command to a remote component to retrieve the remote HSM key component. Subsequent to receiving the cryptographic key component, the cryptographic circuitry can construct a trusted execution environment (TEE) instance and store the remote HSM key component in the TEE instance. The cryptographic circuitry can use the remote HSM key component to perform the cryptographic operation and provide a result of the cryptographic operation to the processing circuitry over the interface.
