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