摘要：On how to evaluate the performance of access control model, the method of N-dimensional security entropy is introduced in this paper. By means of the concept of information entropy in information theory, the N-dimensional security entropy in Discretionary Access Control (DAC) model is discussed in this paper firstly. Then, according to the N-dimensional security entropy, the quantitative security performance is measured in RBAC access control model. Through compare the two models (DAC and RBAC) of security performance, the quantitative analysis of RBAC model with N-dimensional security entropy is completed.
