The traditional theory of subjective logic does not consider the fact that subjective evaluation results change with time.We present a new idea to extend traditional subjective logic theory.The traditional two-dimensional opinion space is extended to a multi-dimensional dynamic opinion space.A dynamic trusted evaluation model of entity behavior based on extended subjective logic is proposed and is implemented based on the reputation and risk evaluation mechanism.The experimental results show that the model can process malicious behavior with more sensitive reaction,more accurate detection,and more effective suppression.
