In order to improve the confidentiality of message authentication in vehicle-mounted ad hoc networks, an efficient certificateless hybrid signcryption scheme with provable security is proposed. Based on the model of the vehicle-mounted ad hoc network system, a pseudonymous self-generation algorithm is introduced after the vehicle is registered, and a hybrid signcryption calculation method is adopted in the signcryption algorithm. Through theoretical proof and experimental verification, compared with the existing certificateless signcryption scheme, the proposed scheme not only protects the privacy information of the vehicle, but also reduces the computation cost of the trusted center and the roadside unit, and keeps the time overhead and communication overhead at a low level, which proves the unforgeability and confidentiality of the proposed scheme in the random oracle model, and can resist various attacks.
