Trust value of the role access control model based on trust

Abstract

In order to solve the current situation that the trust computation of access control model based on trust is insufficient to conduct a fine-grained and dynamic access control, the access control (role model RACT access control model based on trust) which is a fine-grained and integrated with the context is built. The trust value and the threshold of activation and decision tree algorithm are added into RACT to improve the single trust value algorithm for multiple algorithms and realize dynamic access control which is combined with the session history. Experiments show that RACT has higher security than the existing trust model.
