摘要：

利用无证书加密系统构造安全传输协议，该协议的响应时间短、开销小，能提高信任评估的效率。由密钥产生中心产生可验证的公/私密钥组，由此组密钥实现所有传输消息的保密性、完整性和不可抵赖性，保证信任数据在无结构P2P网络中的可靠传输。基于串空间理论对协议的安全性进行了证明。

Abstract:

This paper presents a CL-PKC-based secure protocol for sharing trust data in unstructured P2P networks protocol. The short response time and overhead of protocol can effectively improve the efficiency of the trust assessment. The public/private keys are generated by the key generator center. The security, integrity and non-repudiation of messages are guaranteed by these keys. The strand space theory proves the security of protocol.

Key words: trust, security, strand space, P2P, CL-PKC
