An Anonymous Access Authentication Scheme Based on Proxy Ring Signature for CPS-WMNs

الملخص EN

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.
