摘　　要：信任是解决云环境中安全问题的核心技术.为了深入分析云中信任研究的范畴和方法,给出云中信任的概念,基于云中信任的特点,总结了当前云计算面临的信任问题,并进一步讨论了描述信任关系的模型研究中需要考虑的主要问题.根据信任研究的内容将云环境中信任问题的相关研究成果分类,详细介绍了各类研究方法的特点和关键技术.最后,从信任建模机制和面向的信任问题两方面对这些成果进行比较,基于信任产生的四种促进机制分析了现有研究中存在的问题.针对这些问题,本文指出了云中信任研究未来可能的方向,认为研究方法需要将技术信任与社会信任相结合.Trust is a core technology to solve security issues in cloud environments. In order to do the analysis on the categories and methods of the study on the trust, this paper gave a concept of trust in cloud environments. Based on the characteristics of trust in the cloud, the trust-related problems in cloud computing were summarized. The main problems to be considered in the study of trust model were discussed deeply. Then the related researching results of trust in the cloud were classified based on the content of trust study. The paper introduced the features and key technologies of all kinds of researching methods in details. Finally, from the two aspects of modeling mechanism and trust-oriented problems, the achievements were compared. The existing problems in the present study were analyzed based on four types of promotion mechanisms for establishing trust. According to these problems, some future research directions of trust issues in cloud environments were discussed. This paper pointed out that the researching methods need to combine technology trust with social trust.
