Abstract :
Trust model has become the focus of network security. The description of trust is given newly with fuzzy set theory for pervasive computing environment. In course of trust synthesis evaluation, the model of subjective trust-rank evaluation based on the interval-valued fuzzy set is proposed in this paper so that the evaluation of users trust-rank becomes more flexibility and more reliable. According to the dynamic character of trust, a novel model and method of trust-rank´s calculation based on interval-valued fuzzy set theory is provided. The application instance shows that proposed fuzzy trust evaluation provides a new valuable way for pervasive computing.
