> 中文摘要: 在开放网络环境中,信任管理模型是信息安全的重要前提与基础.考察了主观信任的模糊性,运用模糊集合理论对信任管理问题进行了建模,给出了信任类型的定义机制和信任的评价机制,定义了主体信任的形式化表示,并提出了信任关系的推导规则,构造了一个完整的主观信任管理模型,为开放网络环境中的信任管理研究提供了一个有价值的新思路.
Abstract:Trust management model is fundamental for information security in open networks. The fuzzy nature of subjective trust is considered, and the fuzzy set theory has been used to model the issues of trust management. The formalized valuation of subjective trust is given, the definition of trust class and the evaluation of trust are discussed, derivation rules of trust relationships are presented and a subjective trust management model is provided. The formal model proposed in this paper provides a new valuable way for studying trust management in open networks.
