ABSTRACT:
With the rapid development of the WLAN, the 802.11s mesh network is emerging. Reliability, adaptability and scalability are the most important attributes of a mesh network. However, the security in an 802.11s mesh network is not well defined or specified, and there is no standard method to authenticate a mesh point that is creating a mesh link. In this paper, we propose solutions for the authentication of mesh points. For the Basic Infrastructure Security Mode, we combine the 802.1X/EAP and neighbor graph to realize the fast mutual authentication between a new mesh point and every its mesh link. We prove that our scheme maintains the security of the standardized EAP authentication algorithm. At the same time, the simulation result shows that the authentication latency of our scheme is much lower than that of the scheme in [2]. In the Basic Decentralized Security Mode (BDSM), 802.11s mesh networks are very similar to ad hoc networks, but they are different in several aspects. We first analyze the differences between them. Based on this analysis, we investigate the main authentication methods used in ad hoc networks and select the pairwise key predistribution model and identity-based model for the WLAN mesh network.
