Establish trust between trusted execution environments and peripheral devices

摘要

In embodiments, techniques are provided for establishing trust between a trusted execution environment (TEE) and a peripheral device. Embodiments are configured to communicate with an attestation server to generate an encryption key and to establish a secure connection with the authentication server using the encryption key to enable communication between the authentication server and the peripheral device. In addition, embodiments are configured to receive a pairwise master key if the peripheral device is authenticated and to receive trusted communication from the peripheral device based at least in part on the pairwise master key. Also, embodiments may be configured to identify a connection to a peripheral device, receive an identifier from the peripheral device, and establish a connection to the attestation server based at least in part on the identifier before the peripheral device is authenticated to the authentication server. have.
