Abstract:

The state-of-art remote authorization protocol for vehicle diagnosis cannot ensure the validation of vehicle hardware and software. We propose a new remote authorization protocol for vehicle diagnosis. We use the measurement mechanism provided by the in-vehicle trusted platform module (TPM) to measure the hardware and software of tne vehicle for validation. Embedding this measurement process into the current remote authorization protocol can achieve a strong authentication to the diagnosed vehicle for the trusted-third-party and ensure the validation on the current status of vehicular hardware and software. The new protocol is automatically proved to comply with the security objectives and the increase in computation and communication costs is moderate.

Key words: security protocol, authentication, authorization, remote vehicle diagnosis, trusted computing
