多Agent系统中基于信任度评估模型的自动信任协商

在动态开放的系统中．由于Agent间交互存在着不确定性，安全成为一个重要问题。在现有的自动信任协商的基础上．考虑主观信任的作用．提出基于信任度评估模型的自动信任协商框架．详细介绍框架中的主要成分及其功能．着重讨论基于信任度评估模型的访问控制，以及在信任度评估模型基础上的两种协商对策：基于信任度评估模型的积极对策和基于信任度评估模型的谨慎对策。分别详细介绍采取上述两种对策的协商过程．并结合一应用实例说明基于信任度评估模型的积极对策的协商过程。

The Automated Trust Negotiation Based on Trust Model in Multi-Agent Sysetm

In dynamic and distributed system, interaction between agents is uncertainty, and the security plays an important role. Based on the traditional automated trust negotiation, takes subjective trust into account and develops the framework of trust model based automated trust negotiation. It presents the main components in the framework and their functions in details, emphasizes on the trust representation in access control policy and the negotiation processes of different negoti- ation strategies based on trust model. It presents trust model-based eager strategy and trust model-based parsimonious strategy. Also, gives the negotiation processes of these strategies. And applies an application instance to show the negotiation process of trust model-based eager strategy.
