Effective recommendation chains for large scale distributed decentralized P2P systems
Keywords:
Security Model, Cryptographic ProtocolAbstract
The security model used for centralized systems is not suitable for P2P networks as it is centralized in nature. The security challenges in the P2P networks are secure reputation data management, availability of reputation data, Sybil attacks and identity management of peers. In this paper we present a cryptographic protocol for ensuring secure and timely availability of the reputation data of a peer extremely at low cost. We also investigate Reputation Systems for P2P networks more ambitious approach to protect the P2P network without using any central component, and thereby harnessing the full benefits of the P2P network. The results in the form of simulations reveal that the new cryptographic protocol is secure and efficient in a decentralized peer – to – peer network.
