[0071] Attached below figure 2 The models and methods provided by the present invention are described in detail.
[0072] figure 2 Based on the role-based access control model, tasks, role libraries, and session lists are added, and roles are divided into static roles and dynamic roles. First, we first use dynamic description logic SHOIQ -DL formally describes the entire model, establishing SHOIQ -DL ERBAC The purpose of the knowledge base is to automatically handle the role constraint mechanism in access control. Secondly, based on this model, the system administrator statically assigns permissions to roles to form various forms of the above-mentioned roles, and saves these roles in the role library. In order to make the assignment of roles and permissions within a reasonable range of granularity, this requires the system administrator to have certain experience.
[0073] The administrator also needs to statically add some basic roles, such as the roles correspondin...
