Identity Based Authenticated Key Agreement for MANET

Abstract

A mobile ad-hoc network (MANET) is a convenient infrastructureless communication network. We can construct MANET on demand without support from central servers. MANETs can be applied in critical communication situations such as battlefield, emergency and rescue missions. In the mean time, MANET’s have the following inherent characteristics: open medium, absence of fixed central structure, dynamically changing topology, constrained capabil- ity, etc, so MANETs are highly vulnerable to various security threats.To solve various security problem many key agreement protocols are presented. We de- scribe an authenticated key agreement (Ak) protocol by modifying Smart’s AK protocol. We will also discuss the security of the protocol.
