In this paper, we propose a handover authentication scheme with location privacy preserving based on the proxy ring signature scheme for EAP-based wireless networks. First, we integrate an efficient ring signature and a proxy signature into a proxy ring signature scheme, which allows the mobile node (MN) to be authenticated without revealing its identity and location privacies due to the inherent anonymity of the proxy ring signature. Second, our scheme only requires point multiplication operations on the resource-constraints MN, thus, it is suitable for low-power mobile devices in the wireless networks. Finally, an extensive simulation is given to validate the performance of the proposed scheme. The results demonstrate that our scheme is relatively efficient in terms of computation and communication overhead.
