Research on Modeling of Multiparty Trust Negotiation Based on Coloured Petri-net in P2P Network

Current academic research about automated trust negotiation is mainly focused on duplex sensitive information disclosure. However, real world automated trust negotiation often involve more than two parties. Decomposition is insufficient to reduce an automated multiparty authorization into standalone two-party trust negotiations, because individual negotiations may depend on one another, and therefore need to be interleaved in a certain order for the overall negotiation to succeed. In this paper, we define an extended DARCL policy language, and propose a new modeling method of multiparty trust negotiation based on Coloured Petri-net in P2P network environment.
