The Internet of Vehicles (IoV) has been considered as the most promising architecture for the next generation of Intelligent Transportation System (ITS). However, due to its decentralized feature, the security problem is always the bottleneck problem in IoV. In this paper we consider the secure data exchange protocol in decentralized Vehicle to Vehicle (V2V) Network with physical layer security approach. With skillfully designing of precoding at transmitter, only the desired OBU can receive valid data, meanwhile the attackers can only receive a superposition signal which cannot recover the original data. After N N 1 time slots, each OBU can recover the data from all other OBUs. Performance analysis has been conducted for the proposed protocol in view of theory and simulation. The transmission efficiency analysis result shows that the time slots cost of proposed protocol is less than the naive data exchange. Besides, the security analysis demonstrate that the proposed protocol can successfully prevent instantaneous attack as well as continuous attack.
