Abstract

Mobile Adhoc Network (MANET) consists of a collection of mobile nodes which do not require intervention of any existing infrastructure or centralized access point such as base station. MANET routing protocol are responsible for communication between mobile nodes. But MANET Routing Protocols are highly vulnerable to various attacks on layers of OSI model. Therefore security of routing protocol becomes must. This paper considers a secure routing protocol for Ad hoc on demand distance vector (AODV) routing protocol known as Identity-based key management (IKM) which is a combination of ID-based Cryptography and threshold cryptography and authenticates all routing message. Major concentration in this paper is on black hole attack. We attempt to show how black hole attack is prevented in IKM system. We use NS2 simulator to show the results for same.
