Abstract:

Wireless Mesh Network (WMN) is a promising technology in providing high-bandwidth Internet access over a specific coverage area, with relative lower investment cost as compared with traditional wireless access networks. Authenticated key establishment (AKE) schemes enable two entities (e.g., a client and a server) to share common communication keys in anauthentic way. Due to mobility of Mesh Clients (MCs), a WMN needs to have fast and efficient key establishment and authentication scheme to provide adequate security in client’s handoff while meeting the Quality of Service (QoS) requirements. In this paper, we propose a novel distributed authenticated key establishment scheme (AKES) based on hierarchical multivariable symmetric functions (HMSF), which enables fast key agreement and mutual authentication between network nodes in multi-operator maintained WMNs. In this key establishment scheme, network entities in a WMN such as MCs and mesh access points (e.g. mesh routers) can authenticate each other and establish pairwise communication keys without any interaction from the centralized authentication center, which substantially reduces the communication overhead and authentication delay.
