Title:
Detection And Optimisation Scheme Against Sybil Attack on MANET

Abstract:
It is quite challenging task to achieve security in a Mobile ad hoc network due to its wireless nature, lack of infrastructure and its topology which changes dynamically. Due to its wireless nature MANET is exposed to several attacks. Among them a harmful attack take the advantages of the above mentioned characteristics is the Sybil Attack. In this attack a malicious node uses several identities at a time and increases lot of misjudgments among the node of the network or it may access the identity of the other legitimate nodes and create false expression of that node in the network. In this paper two approaches are discussed to encrypt the data one is Advanced Encryption Standard (AES) and second is Rivest Cipher 5 (RC5) and one optimization technique is discussed that is Genetic Algorithm (GA).
