Then the integrity of the message must be verified every time a message is received. First, before information transmission, mutual authentication must be performed, and a corresponding session key must be generated for subsequent information transmission.

The transmission of wrong information will mislead the driver to make the wrong decision, bringing corresponding troubles and even dangers. In VANETs, the network environment is open attackers can capture various messages transmitted in the network and can forge a legitimate vehicle to send wrong information. With the popularity and development of VANET, it plays a key role in user travel planning and road safety.Īlthough VANETs have various obvious benefits, their security and privacy issues are still the keys to whether they can be widely used. The main goal of VANET technology is to improve traffic efficiency and increase driving experience. Therefore, the vehicle can obtain the corresponding road information from the cloud server through the RSU and can also send the relevant information recorded by itself to the cloud server. In the VANETs, the vehicle is equipped with an on-board unit (OBU), so the vehicle can be regarded as a mobile network node that can communicate. This is the vehicular ad hoc network, which consists of vehicle-to-vehicle (V2V) communication and vehicle-to-infrastructure (V2I) communication.
Therefore, researchers apply artificial intelligence, wireless networks, and sensor technology to road vehicle management, so that vehicles can share information and release relevant road information to alleviate traffic problems. At the same time, the rapid increase in the number of vehicles on the road has also made the traffic situation more complicated, and there will be many traffic problems, such as traffic accidents and road congestion. Introductionĭue to social and economic development, motor vehicles are rapidly spreading. Finally, security analysis and performance analysis show that our protocol is secure and efficient. This protocol can complete mutual authentication and generate a session key. In this paper, we propose a new provably secure authentication protocol to negotiate a session key before transmitting traffic information. Therefore, it is necessary to propose a protocol to protect vehicle data during the information reading phase.
In the process of reading traffic information, there will be some private and sensitive information, which may be intercepted or tampered with in untrusted public channels. However, there are few studies on cloud servers obtaining vehicle information through the roadside unit (RSU). Currently, most research on VANETs obtains data through cloud servers.

VANETs provide a great convenience for drivers and passengers, making it easier to choose routes. In particular, the application of vehicular ad hoc networks (VANETs) is very convenient for real-time collection and analysis of traffic data. While cloud computing and Internet of Things (IoT) technologies have gradually matured, mobile intelligent transportation systems have begun to be widely used.
