Abstract

Wireless mesh network (WMN) provides a low-cost, convenient solution to the last-mile network connectivity problem. As such, existing route protocols designed to provide security and privacy protection for ad hoc networks are not applicable in WMNs anymore. In this paper, we propose a solution for security and privacy protection for WMNs. The scheme relies on group signatures and anonymous mutual key agreement to deliver security and privacy protection. By enforcing access control using user credentials, the user's identity is only disclosed to mesh routers. Finally, we analyze our scheme in terms of security, privacy and performance.
