【摘要】 在开放网络中,信任管理是信息安全的重要前提与基础·通过考查主观信任的模糊性,首次将语言变量、模糊逻辑引入主观信任管理研究中,提出了信任的度量机制,运用模糊IF-THEN规则对人类信任推理的一般知识和经验进行了建模,提出了一种灵活直观,具有很强描述能力的形式化的信任推理机制,为主观信任管理研究提供了一种有价值的新思路·更多还原

【Abstract】 Trust management model is fundamental for information security in open networks . In this paper, the fuzzy nature of subjective trust is considered, and the co nceptions of linguistic variable and fuzzy logic are introduced into subjective trust management. A formal trust metric is given, fuzzy IF-THEN rules are appl ied in mapping the knowledge and experiences of trust reasoning that humanity us e in everyday life into the formal model of trust management, the reasoning mech anisms of trust vectors are given, and a subjective trust management model is pr ovided. The formal model proposed provides a new valuable way for studying subj ective trust management in open networks.更多还原
