The Public Key Infrastructure (PKI) and Certificate Revocation Lists (CRLs) are used to secure vehicular ad hoc networks (VANETs). The authentication of a received message is performed in any PKI system by checking if the sender's certificate is included in the current CRL and validating the authenticity of the sender's certificate and signature. In this paper, we propose an Expedite Message Authentication Protocol (EMAP) for VANETs that uses an efficient revocation checking mechanism to replace the time-consuming CRL checking process. Furthermore, EMAP employs a new probabilistic key distribution that allows non-revoked OBUs to safely share and update a secret key. When compared to traditional authentication systems that use CRL, EMAP can dramatically reduce the message loss ratio due to the message verification latency. EMAP has been proven to be secure and efficient through security analysis and performance measurement.
