| 摘 要： | 将风险理论用于普适计算需要解决的核心问题是对“风险”的定义，云理论是一种定性与定量之间相互转换的有效工具，该文借鉴云理论的概念对普适计算中上下文信息的动态变化进行判断，综合多种风险信号，给出风险信号和“风险”的定义。跟据 “信任风险”和基于云理论的信任模型提出协同信任模型，并列举了一个模型实例。

| Abstract: | The definition of risk is one of the most important problems that need to be solved in the application of risk theory in pervasive computing. Cloud theory is an effective tool in transforming between qualitative concepts and their quantitative expressions. This paper uses the concept of cloud theory to estimate dynamic context and presents the definition of risk signal. By integrating various risk signals, the definition of risk is got. A coordinated trust model including both trust model based on cloud theory and risk recognition method is presented. The coordinated trust model to carry on the experiment is simulated. |
