To secure vehicle ad hoc networks, the Public Key Infrastructure (PKI) and Certificate Revocation Lists (CRLs) are utilised (VANETs). Checking if the sender's certificate is included in the current CRL and evaluating the authenticity of the sender's certificate and signature is how every PKI system authenticates a received message. In this research, we propose an Authentication Protocol Using Expedite Message for VANETs that replaces the time-consuming CRL checking method with an efficient revocation checking technique. Authentication Protocol Using Expedite Message also uses a new probabilistic key distribution that allows non-revoked OBUs to share and update a secret key safely. Authentication Protocol Using Expedite Message can drastically lower the message loss ratio owing to message verification latency when compared to typical authentication systems that use CRL. Through security research and performance assessment, Authentication Protocol Using Expedite Message has been demonstrated to be secure and efficient.
