Embodiment Construction

[0045] The present invention will be further described in detail below in conjunction with the above-mentioned accompanying drawings. It should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0046] Such as figure 1 As shown, the vehicle ad hoc network mainly includes three components: on-board unit (OBU), roadside unit (RSU) and trusted center (TA). However, the security authentication protocol described in the present invention mainly involves vehicle-to-infrastructure communication (V2I). In the present invention, the trusted center is responsible for system initialization, distribution and management of keys, and tracking of malicious vehicles; the on-board unit is responsible for collecting relevant data, generating partial signatures for cor...

Abstract

The invention relates to a method suitable for trusted message broadcasting and security authentication of a vehicle ad hoc network, which belongs to the field of information and communication of an unmanned vehicle ad hoc network. The vehicle obtains the session key through two-way authentication with the trusted center, and the roadside unit collects the partial signature of the specific message, uses the threshold signature technology to generate a credible complete digital signature, and broadcasts it to the vehicles within the communication range. Vehicles receive legal information through security authentication, enhancing road traffic safety and driving efficiency. This method can guarantee the integrity and non-repudiation of information, and at the same time protect the privacy of vehicles that provide partial signatures. In addition, this method has the characteristics of traceability, unlinkability, resistance to replay attacks, and tampering attacks.

Description

technical field [0001] The invention relates to a method suitable for broadcasting of trusted messages and security authentication of vehicle ad hoc networks, aiming at information such as road conditions, driving conditions, emergencies and other information interactively communicated between unmanned vehicles, belonging to unmanned vehicle ad hoc networks field of information and communication. Background technique [0002] With the increase of domestic car ownership, intelligent transportation system has become one of the most promising directions for urban transportation development. Vehicular Ad Hoc Networks (VANETs) is an implementation form of Mobile Ad Hoc Networks (MANETs). It is widely used because of its autonomy and no fixed structure, multi-hop routing, dynamic changes in network topology, limited network capacity, and good scalability. The vehicle ad hoc network is mainly composed of three parts, that is, several on-board units (On-board Unit, OBU) installed ...
