Abstract

With the rapid booming of intelligent traffic system, vehicular ad hoc networks have attracted wide attention from both academic and industry. However, security is the main obstacle for the wide deployment of vehicular ad hoc networks. Vehicular ad hoc networks security has two critical issues: access authentication and privacy preservation. How to ensure privacy preservation and improve the efficiency of authentication has become the urgent needs. However, the existing access authentication schemes for vehicular ad hoc networks with different flaws cannot maintain the balance between security and efficiency. Thus, an anonymous access authentication scheme for vehicular ad hoc networks under edge computing based on ID-based short group signature mechanism is proposed in this article to improve the efficiency and anonymity of access authentication. Multiple pseudonyms are presented to preserve the privacy of vehicle node. Besides, a new method is designed to identify and revoke malicious vehicles in the evaluation manner. The core protocols of the proposed scheme are proved to be secure by SVO logic. According to the computation cost and transmission overhead analysis, we indicate that our scheme owns better performance. Moreover, in this article, we combine vehicular ad hoc networks with edge computing together to provide a new clue for the development of mobile edge computing.

Highlights

The increasing requirement for improving security and privacy for user has brought wide interest on anonymous access authentication for vehicular ad hoc networks (VANETs)
Edge computing can move the large amount of calculating pressure from the vehicle terminal to the roadside infrastructure,[8,9] which is considered to be an ideal solution to the computational-cost process in VANETs during access authentication
We combine the edge computing with VANETs and propose a novel access authentication scheme (AAAS) for VANETs under edge computing that focus on preserving privacy and improving the access authentication efficiency

Summary

Introduction

The increasing requirement for improving security and privacy for user has brought wide interest on anonymous access authentication for vehicular ad hoc networks (VANETs). Massive data generated by vehicles accessed into VANETs require real-time processing to make decisions. The roadside unit (RSU) is a roadside infrastructure, acts as the role of edge node, that can provide edge computing and access services for vehicles. The current technology of VANETs is still not mature enough and facing many security challenges such as access authentication, privacy preservation, traceability, unlinkability, and identification and revocation of malicious nodes. Concrete scheme of access authentication and privacy preservation has become a hotspot.[13]
