Improved User Security Management in Open Distributed System

摘要：

This paper proposed a model for user security management.This model can establish the blacklist and white list to achieve the control of the user subsequent actions through monitoring the changing of user trust level.It also can establish trust policy based on assets importance and user trust level,specify the relationship between user trust and assets value and take it as a dynamic trust constraint for access control.The experiments show that this model combines trust level with access control mechanism;it can enhance the user security management.
