Abstract

The invention discloses an IOV (Internet of Vehicles) anonymous authentication system with a controllable link, and an IOV anonymous authentication method, and relates to the IO field. The system includes a system initialization module which is used for completing the initialization work of an IOV system and a TA (trusted authority); a registration module which is used for completing the registration of an OBU (onboard unit) and an RSU (roadside unit) to the TA; an OBU joining module which is used for obtaining a group certificate from the RSU when the OBU enters the communication range of a new RSU; a signature module which is used for completing the signature of a vehicle about a message; an authentication module which is used for completing the signature information authentication afterthe OBU receives the signature information; a link module which is used by an SP (service provider) to determine whether the two signature messages are linkable or not; an identity tracking module which is used for completing the process that the TA exposes the real identity of a signer of a valid signature message. The construction of the system uses a more lightweight elliptic curve operation to make the authentication process more efficient.

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...
