AERC-Hybrid Technique to Prevent Sybil Attack in MANET

Completely self-organized mobile ad hoc networks (MANETs) signifies multifaceted distributed systems which can be part of infinite multifaceted system, such as a difficult system-of-systems used for crisis organization operations. Due to the complex environment of MANETs and its resource constraint nodes, security solutions are required to protect the network. Since MANETs require a single, divergent, and constant identity per node in order for their safety protocols to be feasible, Sybil attacks create a grave threat to such networks. A Sybil attack is an attack in which intruder can create multiple identities at a time to increases the misjudgment in the network or can exchange identities in order to weaken the recognition process, thereby supporting short of  liability in the mobile ad hoc network. We introduce a HYBRID Algorithm that is Advanced Encryption Rivest Cipher (AERC) by integrating Advanced Encryption Standard (AES), RC5 and Genetic Algorithm (GA). We propose this Hybrid method for the improved security purpose. Performance simulation is taken place in the MATLAB environment.
