Ad hoc networks are vulnerable due to their structure less property. A Mobile Ad-Hoc NETwork (MANET) is an infrastructure less self-configured collection of mobile nodes that can arbitrarily change their geographic locations such that these networks have dynamic topologies and random mobility with constrained resources. Security has become a primary concern in order to provide protected communication between mobile nodes in an aggressive environment. The absence of any central coordination mechanism and shared wireless medium makes MANETs more vulnerable to cyber attacks than wired networks. Different mechanisms have been proposed using various cryptographic techniques to countermeasures these attacks against MANET.
