A Review on Impersonation Attack in Mobile Ad-Hoc Network

摘要

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. Impersonation attack is special case of integrity attacks where by a compromise node impersonates a legitimate node one due to the lack of authentication in current ad hoc routing protocol. In this paper, we are describing the causes of impersonation attack and their vulnerable effects which give chance to a malicious node for doing other attacks too. We confirm with simple risk analysis that impersonation attacks offer attractive incentives to malicious criminals and should therefore be given highest priority in research studies. Our approach is to detecting and eliminating impersonation attack using secure routing protocols.
