Efficient message authentication method for vehicular ad hoc network based on edge computing

Abstract

The invention discloses an efficient message authentication method for a vehicular ad hoc network based on edge computing, which comprises the steps of system initialization of participating entitiesof the Internet of vehicles, wherein the step comprises two processes such as parameter generation and vehicle pseudonym and signature generation; and (2) message authentication of an RSU (Roadside Unit) and a vehicle, wherein the step comprises four processes such that the RSU elects an edge computing vehicle (ECV), the ECV executes a task, the RSU checks an authentication result of the ECV and vehicle message authentication is performed. The signing portion of the invention adopts an elliptic curve cryptography based operation, thereby enabling the computation and transmission overhead to below; further the ECV is elected according to a fuzzy logic control theory to achieve local optimal election; the ECV is set to help the RSU to achieve quick and accurate message signature authentication; and the RSU reduces the redundant authentication of the whole system to the maximum extent through broadcasting the authentication result, and the operating efficiency of the whole vehicular ad hoc network is improved.

Description

technical field [0001] The invention relates to vehicle network communication security technology, in particular to an efficient message authentication method for vehicle network based on edge computing. Background technique [0002] With the development of the automobile industry and the improvement of the economic level, the number of automobiles continues to increase, and people's demand for automobile safety and driving comfort is becoming more and more urgent. The Internet of Vehicles (VANET, Vehicular Ad Hoc Network) emerged as the times require, and has become a research hotspot that the government, research institutions and vehicle manufacturers have paid close attention to. A typical Internet of Vehicles consists of three parts: Trusted Authority (TA, Trust Authority), Roadside Unit (RSU, Roadside Unit) and Roadside Unit (OBU, On BoardUnit). The OBU of the vehicle is mainly responsible for two kinds of communication, namely, vehicle-to-vehicle communication (V2V) a...

Problems solved by technology

In order to solve these security and privacy issues in the Internet of Vehicles, in recent years, many researchers have proposed authentication schemes with their own characteristics, but these schemes basically have redundant authentication, the calculation efficiency is not high enough, and the performance requirements cannot be met in extreme cases.

[0004] In order to solve the problem of redundant authentication and computing efficiency in the field of vehicle network message authentication, this scheme proposes an efficient message authentication scheme for vehicle network based on edge computing
