Secured Authentication Method in V2X Communication Scenario

With the rapid advancement of Internet of Vehicles (IoV), vehicles are embedded everywhere in the transportation system as ubiquitous things connected based on the V2X (Vehicle-to-Everything) communication technology. Risk, cybersecurity, and privacy are major challenges for such a development. Much research has focused on safety, efficiency, and mobility applications in V2X communication. Protection of integrity, authenticity, and tamper-proofing of V2X communication messages is carried out in trust model of credential management system. This system defines legal, policy, and technical requirements for the management of public key certificates for V2X communication applications. This paper provides an overview of IoV with emphasis on system architecture, enabling cryptographic algorithms technologies, and certificate format of existing systems. An overview of cybersecurity challenges for V2X communication and related security solutions is also presented. Further, the paper discusses the existing privacy policies and certificate management strategies, and presents the significance of horizontal integration among V2X services in the future.
