摘要
Automated trust negotiation （ATN） offers an at- tractive means for trust establishments, which establishes mu- tual trust among strangers wishing to share resources or con- duct business, but it comes at the cost of non-trivial computa- tion and communication overheads. The deployment of ATN strategies on a resource-constrained mobile device may lead to user-obstructive latency for operations. In this paper, we propose a trust negotiation strategy called trust target Petri nets negotiation strategy （TPNNS）. It highly reduces the ne- gotiation latency in the mobile device compared with other negotiation strategies, since it considers all the alternative re- sponses at each step and chooses the best one. TPNNS sup- ports cycle avoidance and employs skipped TPN which is a new approach presented in this paper. What is more, it is complete and ensures no irrelevant credentials are disclosed during the trust negotiation.
