Abstract: In order to overcome the security problem of radio frequency identification technology in the internet of vehicles, a security authentication protocol based on key distribution center was proposed. First the label without the legal key was filtered by the updateable private key stored in the key distribution center, and then the identity of the tag was authenticated through the background server. While solving the security problems, such as counterfeit attacks, replay attacks, and tracking attacks in the traditional protocol, the denial of service (DoS) attacks existing in the internet of vehicles were also solved. Through the BAN logic proof, as well as the comparison of security and performance analysis, it shows that this protocol can provide effective security protection in the internet of vehicles, which greatly reduces the computing burden of the background server facing multiple tags.

Key words: radio frequency identification technology, internet of vehicles, security authentication protocol, denial of service attack
