中文摘要：

针对目前信息安全类游戏缺乏协同机制以及协同过程中敏感信息易泄露的问题，基于改进的信任管理和信任协商技术，设计了一种基于信任协商的网络协同攻防游戏模型，将信任协商技术应用到协同过程中，降低了协同过程中敏感信息泄露的风险，并探讨了自适应信任协商策略模式。通过实验分析证明了自适应信任协商在效率方面的优势。

英文摘要：

Most information games at present lack of cooperation and some sensitive information are easily leaked during the cooperation. Based on improved technology of trust management and trust negotiation this paper designs an offensive and defensive game model of network cooperation based on trust negotiation. The model applies trust negotiation technology to network cooperation. It reduces the risk of sensitive information leakage during cooperation. This paper also researches on self-adaptive trust negotiation policy method and proves through the experiment that it has superiority on efficiency.
