基于云模型的主观信任管理模型研究

Research on Subjective Trust Management Model Based on Cloud Model

在开放网络中,信任管理是信息安全的重要前提与基础。主观信任具有模糊性和不确定性的双重特征。将定性定量转换模型-云模型引入主观信任管理研究中,提出了一种新的主观信任的表示方法,较好地解决了信任表达中的模糊性和不确定性难题,进而提出了一种灵活直观,描述能力较强的形式化定性信任推理机制,为主观信任管理研究进行了有益的探索和尝试。

Trust management model is fundamental for information security in open networks. A formalism method for subjective trust use cloud model was proposed which was the transforming model between qualitative and quantitative. The exploration of uncertainty and fuzziness characters which was always considered by two internal properties of trust provided a step in the direction of proper understanding and definition of human trust. The qualitative reasoning mechanisms of trust cloud were given to enable trust-based decisions.
