The growth in intelligent transportation systems and the increasing number of vehicle users has made data forwarding a critical area of research for the Internet of Vehicles. However, due to the high-speed movement of vehicle nodes, the network topology changes rapidly, leading to poor network connectivity. Additionally, the wireless communication nature of the Internet of Vehicles makes data forwarding and user information susceptible to eavesdropping and leakage. Furthermore, some vehicle users may refuse to forward data. Therefore, it is crucial to ensure data forwarding reliability, user identity privacy, and users’ participation in the Internet of Vehicles. In this context, a vehicle networking data forwarding scheme is proposed that ensures anonymity and trust evaluation. The scheme uses certificateless signature technology to authenticate regional vehicle members and roadside units anonymously. Vehicles forward messages through roadside units to trusted authorities (TA). The traffic management center (TMC) evaluates the reliability of the received message and forwards it to the corresponding vehicle node to improve the timeliness of forwarding. Finally, the trusted organization calculates the vehicle node’s trust level through the message’s reliability and updates the vehicle credit account. The use of certificateless signature technology reduces computing overhead, and the TMC classification and evaluation of messages ensure reliability and integrity. Updating users’ credit accounts also improves their enthusiasm for participation. Security analysis confirms that the scheme achieves authentication, anonymity, data reliability, non-repudiation, and traceability of user identity.
