Comparative Study and Evaluation of Solving Sybil Attack on Peer-To-Peer Network

In computer networks, computing devices allows to exchange data with one another via a data link. Peer-to-peer model (P2P architecture) is a frequently used computer networking architecture in which each workstation, or node, has the same adaptability, capabilities and responsibilities. The idea behind this attack is that a single malicious identity can present multiple identities, and thus gain control over part of the network. Various counter measures to avoid the damages through this attack are considered [3]. The algorithms has already been proposed for mitigating the impact of Sybil attack in peer to peer network, but the detection of Sybil node is only on the sender side. In this paper, the algorithm is introduced which can detect the Sybil node on peer to peer network in both sender as well as receiver side. This will help to identify the malicious node and to maintain the consistency of information on network.
