Abstract
Technologies for secure authentication and programming of an accelerator device are described. In one example, a computing is disclosed comprising an accelerator device to: provide a unique device identifier to an accelerator services enclave (ASE) of a processor of the computing device; authenticate with the ASE by: performing a secure key exchange with the ASE to establish a shared secret tunnel key; verifying an enclave certificate of the ASE; and providing an attestation response to the ASE indicative of an accelerator device configuration; establish a secure channel with the ASE protected by the shared secret tunnel key; receive bitstream image key and bitstream data key from the ASE via the secure channel; program the accelerator device via the secure channel using the bitstream image key; and exchange data with a tenant enclave of the processor, the data protected by the bitstream data key.
