An Efficient Key Management Scheme with Key Agreement to Mitigate Malicious Attacks for Wireless Mesh Network

Abstract

In the recent times the IT industry has been witnessing rapid development in wireless communication technologies such as 3 G, 4 G, etc. Wireless Mesh Network is one such promising wireless communication technology which provides high bandwidth internet connectivity in a sizable geographic area at a much lower cost than with classic WiFi networks. WMN consists of wireless entities such as Mesh Routers (MRs), Mesh Clients (MCs), Internet Gateways (IGs) are organized in an arbitrary mesh topology and form the wireless mesh back bone. Due to the mobility of the Mesh Clients, great challenges arise in securing the WMNs from various kinds of attacks. In this work a security mechanism is presented to ensure that induced network is connected and well protected from potential eaves dropping attacks, and this is accomplished by introducing an efficient key management scheme with key agreement. The simulation results show that the scheme implemented in this work, out performs previous schemes thus providing a network that is resistant against malicious eavesdropping attack.
