Abstract

The invention discloses a distributed aggregation authentication method having a privacy protection function for a vehicle-mounted self-organizing network. The method comprises the following steps: a step of trusted root mechanism arrangement, a step of road side unit arrangement, a step of vehicle arrangement, a step of internal pseudonym and authentication key updating, a step of a vehicle obtaining secrets of members and authorization terms, a step of the vehicle generating signatures and updating the secrets of the members, a step of tracking and a step of message verification and information storage. The distributed aggregation authentication method is characterized in that conditional privacy is not associable, the method is independent of an ideal and strict anti osmosis device, and no secret key trusteeship problem can be caused. Safe and private communication of a the vehicle-mounted self-organizing network can be realized through the distributed aggregation authentication method.

Description

technical field [0001] The invention belongs to the field of vehicle ad hoc network information security, in particular to a distributed aggregation authentication method with privacy protection in the vehicle ad hoc network. Background technique [0002] A vehicular ad hoc network is an ad hoc network for inter-vehicle communication that can enhance the driving experience by improving traffic safety and efficiency. The vehicle ad hoc network is mainly composed of vehicles and roadside units. Each vehicle can exchange information with other vehicles and roadside units in the vicinity, through which information can reduce the possibility of accidents for drivers, and can also help drivers deal with common emergencies. [0003] In order to achieve the above-mentioned goals of VANET, it is particularly important to ensure that safety-related messages are received safely, and these messages should have authentication, non-repudiation and integrity. Otherwise, a malicious vehic...
