Abstract

Access security and privacy have become a bottleneck for the popularization of future Cyber-Physical System (CPS) networks. Furthermore, users’ need for privacy-preserved access during movement procedure is more urgent. To address the anonymous access authentication issue for CPS Wireless Mesh Network (CPS-WMN), a novel anonymous access authentication scheme based on proxy ring signature is proposed. A hierarchical authentication architecture is presented first. The scheme is then achieved from the aspect of intergroup and intragroup anonymous mutual authentication through proxy ring signature mechanism and certificateless signature mechanism, respectively. We present a formal security proof of the proposed protocol with SVO logic. The simulation and performance analysis demonstrate that the proposed scheme owns higher efficiency and adaptability than the typical one.

Highlights

With the prosperous development of mobile communication and versatile mobile devices [1, 2] and the diversification of the network environment [3,4,5], the requirement of accessing ubiquitous network becomes more and more imperative for Cyber-Physical Systems (CPS) [6]
To achieve mutual authentication between MC and visiting network based on Proxy ring signature (PRS), we build the group of proxy rings for network entities in terms of the hierarchical mobile network architecture shown above
We propose a novel anonymous access authentication scheme based on proxy ring signature for CPS Wireless Mesh Network (CPS-Wireless Mesh Network (WMN))

Summary

Introduction

With the prosperous development of mobile communication and versatile mobile devices [1, 2] and the diversification of the network environment [3,4,5], the requirement of accessing ubiquitous network becomes more and more imperative for Cyber-Physical Systems (CPS) [6]. Owing to the advantages of low cost, expansible, self-healing, fine mobility support, and high efficiency, Wireless Mesh Network (WMN) is regarded as a critical accessing technology of the generation CPS network [7, 8]. A symmetric key generation scheme based on hierarchical multivariable function for WMN is presented in [14], which achieves efficient mutual authentication and key generation for entities, whereas the scheme is not suitable for the scenario when the network users grow rapidly. The literature WMN access authentication schemes suffer from security, privacy, efficiency, and adaptability issues. In terms of the security issues shown above, an anonymous authentication scheme based on proxy ring signature is proposed in this paper. The scheme utilizes a highefficient proxy ring signature mechanism to achieve proxyauthorization and anonymous authentication which are able to preserve mobile users’ privacy.
