A vehicle networking anonymous authentication system and method with controllable links

Abstract

The invention claims protection of an anonymous authentication system and method for the Internet of Vehicles with controllable links, and relates to the field of Internet of Vehicles. The system includes: a system initialization module, which is used to complete the initialization work of the Internet of Vehicles system and the trusted organization TA; a registration module, which is used to complete the registration of the vehicle-mounted unit OBU and the roadside unit RSU to the TA; the OBU joining module is used for When the OBU enters the communication range of a new RSU, obtain the group certificate from the RSU; the signature module is used to complete the vehicle's signature on the message; the authentication module is used to complete the signature information after the vehicle-mounted unit receives the signature information Verification; a linking module, used for the service provider SP to judge whether two signed messages are linked; an identity tracking module, used for the trusted authority TA to disclose the true identity of the signer of a valid signed message. The structure of the present invention adopts lighter-weight elliptic curve calculation to make the authentication process more effective.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Vehicles, in particular to an anonymous authentication method for communication between vehicles under the Internet of Vehicles. Background technique [0002] With the rapid development of intelligent transportation systems, vehicles are gradually playing an increasingly important role in people's lives. Because the self-organizing network of vehicles (Internet of Vehicles) can make our driving environment safer and more comfortable, it has attracted extensive attention from various industries such as industry and academia. [0003] Due to the self-organization of the Internet of Vehicles, the high-speed mobility of vehicles, the strangeness between neighbors, and its communication channel is open, so attackers can easily capture, change, replay and delete the data transmitted in the Internet of Vehicles. information, which can lead to a large number of security issues, which can have a s...
