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.
