In this paper, we propose a Novel and Efficient Hash-chain based Certificate Management (NEHCM) scheme for vehicular communications. In NEHCM, to protect driver privacy, each vehicle is equipped with a large set of short-time certificates, and most importantly, serial numbers of these certificates satisfy hash-chain relationship. As a result, the certificate revocation becomes an easy task by simply...
