Embodiment Construction

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

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

[0078] TA is a trusted third party with high computing power and sto...

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 vehicle self-organizing network conditional privacy protection method based on a registration list. 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 extraction and effective use of the static and dynamic information of all vehicles on the information network platform by the electronic equipment loaded on the vehicle through wireless technology. People will effectively supervise the running state of vehicles according to different functional requirements, and provide comprehensive services at the same time. VANET connects vehicles to vehicles, and vehicl...
