The Public Key Infrastructure (PKI) and Certificate Revocation Lists (CRLs) are used to protect vehicle ad hoc networks (VANETs). Every PKI system authenticates a received message by checking if the sender's certificate is included in the current CRL and evaluating the authenticity of the sender's certificate and signature. We propose an (EMFU) Expenditure Message for UAV in this paper, which replaces the time-consuming CRL checking approach with a fast revocation checking methodology. EMFU also employs a new probabilistic key distribution, which enables non-revoked OBUs to safely share and update a secret key. When compared to traditional authentication systems that employ CRL, EMFU can dramatically reduce the message loss ratio due to message verification latency. EMFU has been shown to be secure and efficient through security research and performance evaluation.
