Message security in P2P network using distributed private key

Peers are equally privileged, equipotent participants in the application. Identity based cryptography (IBC) was introduced into peer-to-peer networks recently for identity verification and authentication purposes. In this paper we use a method that will provide the security issues for private key with efficient and secure protocol for key issuing in ID-based cryptosystems. We use a simple blinding technique to eliminate the need of secure channel and also multiple authorities approach to avoid the key distribution problem. We also show the experimental results conducted on key distribution and peer registration protocol.
