Abstract:

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.
