Providing Security by HMAC Algorithm in P2P Reputation Management Using Distributed Identities and Decentralized Recommendation Chains

Abstract

The main concern of this paper is to keep the Peer-to-Peer network system more secure and at the same time to keep the speed of Peer-to-Peer network system at the maximum functionality. In this paper we introduce a new encryption protocol for the security of Peer-to-Peer network system called HMAC algorithm, which is low in cost and probably best in function. Peer-to-Peer network systems are decentralized network systems which pose them vulnerable for attackers/hackers. The vulnerability may be in the form of Peers who cheat, who propagate malicious code or sometimes the peers who simply leech on the network. This can be counteracted by our encryption protocol. Moreover we establish a trusted self certification system which minimizes the access of our network to these attackers. The other main problem being decreasing network functionality by dynamically changing number of users that are logging in & logging out. We answer this by sorting them into small groups and limiting the dynamicity in the subgroup. This provides secure transfer of information without any malicious data with efficient functionality of the Peer-to-Peer network system.
