中文摘要： 由于网络系统的开放性、多样性和复杂性，其实体的可信性面临严峻的挑战，为保证整个系统的可信性，对实体运行进行有效的信任关系管理是十分必要的。在虚拟网络环境下，构建了一个基于信任领域和Agent 技术的具有层次结构的实体行为可信性管理框架（MMA）。首先，研究了MMA结构中各结点的逻辑构成及可信性协同机制，提出了基于信任域的多代理网络资源选择模型，针对P2P网络提出了电子商务系统的细粒度信任模型以及基于多维主观逻辑的信任模型。其次，研究了实体行为的可信性度量策略，给出了行为轨迹的获取和表示方法、行为轨迹的化简规则、运行时可信性的监控以及可信性评价模型，提出了可信引擎驱动的可信软件信任链模型以及基于可信包装的可信软件构造方法。最后，研究了基于信任度的信任关系动态管理控制策略，提出了基于检查点风险评估的软件行为可信模型，通过扩展J?sang的主观逻辑实现软件行为信任度的动态更新，提出了基于加权紧密度的信任合并与信任发现机制。研究成果对信任管理理论的发展具有推动意义，对网络安全应用技术、可信软件的开发具有支撑作用。

英文摘要： Due to the openness, diversity and complexity of network systems, the credibility of their entities faces severe challenges. In order to guarantee the credibility of the whole system, it is very essential to establish effective trust relationship management model among the entities. We have constructed a hierarchical management architecture, which is called Manager Monitor Agent (MMA), of entity behavior based on trust domain and agent technology in the virtual networking environment. Firstly, we have studied the logical structure and trusted cooperated mechanism of the nodes in MMA, proposed a trust domain-based multi-agent model for network resource selection, and also presented a fine-grain trust model for e-commerce system and a trust model based on the multinomial subjective logic for P2P network. Secondly, we have studied the credibility measurement strategies of entity behaviors, and proposed the acquisition and expression method and reduction rules of behavior trace, the monitoring and evaluation model of credibility during running, the trust chain model of trustworthy software driven by trustworthy engine and the trustworthy software constitution method based on trust shell. Finally, we have studied the dynamic management and control strategy of trust relationship based on trust degree, proposed a trust model of software behavior based on checkpoint risk evaluation, released the dynamic update of trust degree of software behavior through extending the subjective logic of J?sang, and presented the trust combination and trust discovery mechanism based on weighted closeness. This research has great significance to network security technology and trustworthy software development and promotes the development of trust management theory.
