摘要
目前大多数信任证搜集技术采用传统的信任协商方法收集信任证,这给信任服务器带来很大负载且存在信任证盲目搜索问题。本文介绍了一个信任分布式证明协商算法DPN。基于RTP策略语言,DPN能够智能地对信任关系进行远程证明或本地推演,从而能够提高信任建立的效率。DPN能够给出证明协商过程中的相关信任规则纪录,支持对信任建立过程的验证。分析了算法的正确性和完整性,并通过实验证明了算法带来的性能提升。
The traditional trust negotiation methods bring a heavy burden to the trust server and have the blind credential fetching problem.This paper presents a distributed proving and negotiation（DPN） algorithm based on the RTP policy language.DPN can intelligently do a remote trust proving or a local trust negotiation,which can improve the efficiency for trust constructing.Moreover,through recording all the related rules used in the algorithm,DPN can support the verification of the trust proof.Both the correctness and completeness of the algorithm are analyzed,and the experimental results demonstrate the performance improvement of DPN.
