Self Certification Based BloomCast File Retrieval In Unstructured P2P Networks

Abstract Peer-to-peer P2P networks are exposed to peers who fake advertise malign code or peers who wont contribute. The classic security techniques like client-server networks are not enough for Peer-to-Peer networks because of its centralized nature. BloomCast is a full-text revival scheme which is used in unstructured P2P networks. It duplicates Bloom Filters rather than duplicating the documents among the network. BloomCast greatly minimizes the communication cost needed for duplication. But the main disadvantage is that it is vulnerable to malicious peers. In the proposed method self certification technique is used. Self-certification removes the need of a centralized system for sending the identities. The Self Certification mechanism helps to identify the malicious content and makes the search more effective.
