基于云模型的可信研究综述

A Review of Trusted Research Based on Cloud Model

信任具有主观性、模糊性及随机性,云模型是在随机数学和模糊数学的基础上,用于描述语言值的随机性与模糊性以及二者之间的关系。将信任与云模型结合可以建立一个科学、合理的主观信任评估模型,用于网络环境下各行为主体可信度的判断,提高网络环境的安全性和可靠性。通过对其所涉及的概念、算法、方法改进进行综述,分析可信云模型实现原理以及存在的问题,最后提出了基于云模型可信度研究的方向。

Trust has subjectivity, fuzziness and randomness. The cloud model is based on random mathematics and fuzzymathematics, which is used to describe the randomness and fuzziness and the relationship between them. Combines trust and cloud model can build a subjective trust evaluation model of scientific, reasonable, to the credibility of the behavior sub-ject judgment under the network environment, improve the safety and reliability of the network environment. Through the involved concepts, algorithms, methods of improvement were reviewed, analyzed trusted cloud model implementation princi-ple and the existing problems and finally put forward the re-search direction of reliability based on cloud model.
