SLAB: A secure localized authentication and billing scheme for wireless mesh networks

The future metropolitan-area wireless mesh networks (WMNs) are expected to contain compromise-prone mesh access points (MAPs) with a high frequency of inter-domain roaming/handoff events. This paper introduces a novel secure localized authentication and billing (SLAB) scheme, which aims to address both security guarantee and performance in terms of system compromise resilience capability, interdomain handoff authentication latency, and workload of the roaming broker (RB). With extensive analysis and simulation, we demonstrate that the proposed scheme can be a practical solution for achieving secure roaming and billing in metropolitan-area WMNs.
