| Summary: | Aiming at the problem that vehicles in the vehicular ad-hoc network (VANET) system were vulnerable to malicious attacks when communicating with each other on the public network, a mutual authentication key agreement protocol in the VANET was proposed.A dynamic vehicle group was established by the Chinese remainder theorem to adapt to the rapid changes in the VANET topology.Signature information was used by both parties in communication to quickly authenticate the identity of the message sender, and key agreement was conduct through the semigroup of Chebyshev chaotic mapping.The pseudonym update and private key update mechanism were adopted to protect the privacy and security of the vehicle’s identity.The identities of malicious vehicles were tracked accurately by using signature information, and were revoked quickly by modifying the public key information.In addition, the semantic security of the protocol was proved by the BAN logic model.The simulation results show that the proposed protocol can effectively reduce the communication consumption and significantly reduce the computational consumption compared with the existing similar literature. |
