As the core of intelligent transportation, V2X technology in Internet of Vehicles communication is crucial. This paper analyzes the security challenges of V2X technology, including identity authentication risk, data privacy leakage, network attack threat and so on. In response to these challenges, blockchain-based identity authentication mechanism, data encryption and anonymity processing, strengthening network security protection and other measures are proposed. Through these measures, the safety of V2X technology can be effectively improved to guarantee the stable operation of the intelligent transportation system. The research results show that the comprehensive use of a variety of technical means is the key to cope with the V2X security challenges, and the future technology optimization and cooperation are needed to promote the security development of Internet of Vehicles communication.
