MANET is an independent and infrastructureless network comprising of self configurable mobile nodes connected via wireless links.MANET is susceptible to various attacks because of some loopholes present in MANET like dynamic topology, zero central administration, limited physical security etc. MANET is prone to numerous malicious attacks one such attack among them is SYBIL ATTACK.In Sybil attack multiple identities are presented by a single physical node.This attack has serious impact on network functionality.In this paper principle focus is on preventing Sybil attacks using ElGamal algorithm.The concept of ElGamal algorithm has been used in this paper so as to deal with Sybil attacks.
