Zusammenfassung
In this paper we propose a solution to enable an accurate terminal revocation in the Extended Access Control (EAC). Chaabouni and Vaudenay in [CV09] pointed out the need for an accurate revocation procedure, but failed to provide a complete solution description. We aim at filling this gap. Our solution relies on augmenting terminal authentication with a t-out-ofthreshold signature provided by neighboring terminals. These terminals will be in charge of checking the revocation status of the requested terminal. As Terminals have a real clock embedded and more computational power than Machine Readable Travel Documents (MRTDs), they are better suited for checking revocation status.
