Wireless Mesh Networks (WMNs) have emerged recently as a technology for next-generation wireless networking. In this paper authors propose MobiSEC, a complete security architecture that provides both access control for mesh users and routers as well as security and data confidentiality of all communications that occur in the WMN. MobiSEC extends the IEEE 802.11i standard exploiting the routing capabilities of mesh routers; after connecting to the access network as generic wireless clients, new mesh routers authenticate to a central server and obtain a temporary key that is used both to prove their credentials to neighbor nodes and to encrypt all the traffic transmitted on the wireless backbone links.
