摘要

针对云计算开放环境下的安全问题

为有效分析用户不可信行为和异常行为

实现用户行为信任的科学量化评估

综合考虑信任评估的动态性

提出一种基于相对熵的组合赋权法用户行为信任评估

结合主客观赋权法的权重信息

通过相对熵计算各主客观赋权法权重的贴近度

从而确定各赋权法权重在组合权重中的加权系数

最后对组合权重运用模糊综合评价得到用户的信用度.验证结果实现了模型的具体化

表明了组合赋权法的科学性和可操作性

并对用户的信用度做出了客观评价.

Abstract

Aim at the security issuses in cloud computing

a method based on Combination Weighting Approach of Relative Entropy is proposed to evaluate users behavior trust to analyze the untrust and abnormal behavior effectively

so as to achieve the scientific quantitative evalution for users behavior trust.Combined with the Weighting factor of weighting method which is both subjective and objective

relative entropy is applied to compute the approach degree of weights.Which are set by subjective and objective weighting method

thus the weighting efficient of each weighting menthods weight in conmbination weight can be determined.Finally

fuzzy comprehensive assessment is made for combination weight to get users trust value. Implementation and verification of the model shows that combination weighting method and the model are scientific and operability

and making objective evaluation for the users credit.
