Embodiment Construction

[0076] The technical solutions of the present invention will be described in detail below, but the protection scope of the present invention is not limited to the embodiments.

[0077] Such as figure 1 As shown, VANET usually includes three parts trusted authority (TA), roadside unit (RSU), on-board computing unit (OBU), and its main distribution is as follows: figure 1 As shown, the OBU loaded on the vehicle is responsible for calculating and publishing traffic information. The RSU collects the messages released by the vehicles within its range, and after centralized processing, releases notification information. The OBU obtains information such as current road conditions by processing the notification messages. Information between OBUs and between OBUs and RSUs is transmitted through wireless channels, and information between TAs and RSUs is transmitted through wired channels.

[0078] TA is a trusted third party with high computing power and capacity storage, responsible f...

Abstract

The invention discloses a method for protecting the vehicular ad hoc network conditional privacy based on a registration list. The method comprises the following steps: (1) offline registration, including trusted association TA initialization, road-side unit RSU initialization and on-board unit OBU initialization; and (2) driving process, including mutual authentication, traffic information release, message authentication, notice message generation and message receiving. According to the method, a vehicle user carries out cooperative communication with RSU which are deployed on two sides of aroad through the OBU, so that the driving safety can be effectively improved, and users can conveniently and quickly acquire related service.

Description

technical field [0001] The invention relates to the security technology of the Internet of Vehicles, in particular to a registration list-based conditional privacy protection method for the vehicle ad hoc network. Background technique [0002] As a specific application of mobile ad hoc networks in the field of transportation, the Internet of Vehicles is a new type of multi-hop mobile wireless communication network, which has become a hot spot in the field of wireless network research in recent years. [0003] The so-called Internet of Vehicles (VANET) refers to the electronic equipment loaded on the vehicle to realize the extraction and effective utilization of the static and dynamic information of all vehicles on the information network platform through wireless technology. People will effectively supervise the running status of vehicles according to different functional requirements, and provide comprehensive services at the same time. VANET connects vehicles to vehicles,...
