Secure Localized Authentication and Billing for Wireless Mesh Networks

The future metropolitan-area wireless mesh networks (WMNs) are expected to have compromise-prone mesh access points (MAPs) with high frequency of inter-domain roaming/handoff events. To achieve security without losing efficiency, this paper introduces a novel secure localized authentication and billing (SLAB) scheme. Our scheme aims to address both security guarantee and performance in terms of system compromise resilience capability, inter-domain handoff authentication latency, and workload of the roaming broker (RB). We demonstrate that the proposed scheme can be a practical solution for achieving secure roaming and billing in metropolitan-area WMNs.
