Abstract

We address property-based attestation in the context of an in-vehicle communication system called Terminal Mode that allows mobile devices to "stream" services, such as navigation or music, to car head-units. In Terminal Mode, attestation of the mobile device is needed to enforce driver distraction regulations and traditional binary attestation is not applicable due to frequently needed measurement updates and limited connectivity of car head-units.We present a novel attestation scheme that bootstraps from existing application certification infrastructures available on mobile device platforms, and thus avoids the need to setup and maintain a new service that provides translation from software measurements to properties, and consequently makes realization of property-based attestation economically feasible.
