Abstract:
Technologies are provided in embodiments to establish 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, using the encryption key, a secure connection with an authentication server to enable communication between the authentication server and the peripheral device. Embodiments are also configured to receive a pairwise master key if the peripheral device is authenticated and to receive a trusted communication from the peripheral device based, at least in part, on the pairwise master key. Embodiments may also be configured to identify a connection to the peripheral device before the peripheral device is authenticated to the authentication server, receive an identifier from the peripheral device, and establish a connection to an attestation server based on at least a portion of the identifier.
