A Secure Protocol for Sharing Trust Data in Hybrid P2P Network
The trust data is critical to the trust model of P2P system. In this paper, the authors present an efficient certificateless cryptography scheme and propose a protocol which provides the ability for sharing trust data securely. The protocol avoids the escrow problem identity-based cryptosystem and the secure delivery of private keys. The security of scheme is based on some underlying problems closely related to the Bilinear Diffie-Hellman Problem are computationally hard. It tolerates the Type I and Type II adversary. The proof of security is presented in the random oracle model.
