Abstract |
An ad hoc network is a collection of mobile nodes that dynamically form a temporary network and are capable of communicating with each other without the use of a network infrastructure or any centralized administration. Due to Open medium, dynamic topology, Distributed Cooperation, Constrained Capabilities ad hoc networks are vulnerable to many types of security attacks. Despite the existence of well-known security mechanisms, additional vulnerabilities and features pertinent to this new networking paradigm might render the traditional solutions inapplicable. In particular, in mobile ad hoc network (MANET), any node may compromise the routing protocol functionality by disrupting the route discovery process. The solution proposed Secure Ad hoc On-Demand Distance Vector (SAODV) is an extension of the AODV routing protocol that can be used to prevent Impersonation attack. In this attack, the attacker assumes the identity of another node in the network, thus receiving messages directed to the node it fakes. The methodologies used to achieve these requirements are Hash chains and Digital Signatures. |
