In this paper, we introduce an efficient and dynamic elliptic curve qu‐vanstone implicit certificates distribution scheme for vehicular cloud networks. We are concerned about how to achieve efficiently and dynamically certificates distribution with a reduced cost. We design an efficient mechanism that reduces the communication cost and the computational overhead for more safety and robustness of intelligent transportation systems. Our proposal enables vehicles to request and obtain implicit certificates upon a secure request, which can be used for further signing exchanged messages. Due to the restricted nature of these certificates, a simple and efficient revocation method has been presented. It is literally based on selective revocation message delivery technique that reduces the number of messages needed for revocation phase and solves a bunch of drawbacks of existing solutions. An extensive analysis is performed to demonstrate how the proposed scheme can dynamically carry out an effective certificates distribution. We further discuss and evaluate simulation results to demonstrate the merits gained by the proposed protocol.
