Abstract
An apparatus includes a processor coupled to a memory wherein the processor and the memory are configured to provide a secure execution environment. The memory includes a shared secret value. The processor is configured to receive a certificate, wherein the certificate includes a device identifier and a digital signature. The processor validates the certificate based on the digital signature and the device identifier, recovers a cryptographic key based on the shared secret value and the device identifier, and performs a cryptographic operation based on the recovered cryptographic key.
