中文摘要：
不完全信息的自动信任协商中存在如披露最少证书获得对方最大信任、协商效率等优化问题.利用博弈分析信任协商过程中的协商方的收益,给出权衡资源比重方法,量化了信任协商的计算过程,提出基于动态阈值的信任协商建立方法.动态阈值具有随证书披露与信息完整而进行自主变化的能力,可以减少协商过程的隐私披露.样例分析和仿真试验表明：使用动态阈值方法可以限制证书披露的数量,提高不完全信息下信任建立的效率.
英文摘要：
In incomplete information environment,there are many optimization problems in the process of automated trust negotiation（ATN） based on exchanging digital credentials,like how to disclose minimum credentials and obtain maximum authorized,negotiation optimization,et al.Based on an analysis of the ATN process by game theory,a quantitative approach of trust is proposed to compute trust value of each credential in the ATN process a trust negotiation system is established on the basis of the dynamic strategy.The dynamic-threshold,fluctuating with the negotiation process,is proposed for further optimization to reduce credentials disclosure.The case analysis and simulations show that the dynamic-threshold strategy can restrict the amount of disclosed credentials and improve efficiency of the negotiation process in the incomplete information environment.
