In this paper, we propose a secure and efficient revocation scheme for anonymous vehicular communications, named SEA. SEA is a pseudonymous authentication scheme, but unlike traditional pseudonymous schemes, its CRL size is linear in terms of the number of revoked vehicles and unrelated to the size of vehicle pseudonymous certificate set. SEA supports certificate regional management and keeps the service overhead of RSUs very low. Furthermore, SEA provides strong privacy preservation against the RSUs so that the adversaries can not trace any vehicle even all RSUs have been compromised. Extensive analysis demonstrates that the proposed scheme outperforms previously reported ones in terms of the revocation cost and the RSUs service overhead.
