Abstract

The invention discloses a distributed aggregation authentication method with privacy protection in a vehicle-mounted ad hoc network. The method includes the following steps: setting a root trusted institution; setting a roadside unit; setting a vehicle; updating an internal pseudonym and an authentication key; Obtaining member secrets and authorization periods; vehicle generation signatures and updating member secrets; tracking, message verification, and information storage. The invention has the following characteristics: satisfying conditional non-associated privacy; not relying on ideal and strict anti-penetration equipment; no key trusteeship problem. The invention can achieve the safe and private communication of the vehicle ad hoc network.

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...
