Research and Design of Privilege Management System Based on Role
Introduces the main theory of RBAC model,researches and designs the role-based privilege management system,and analyzes the system architecture,function modules,design of database and other aspects.In this access control model,applies role hierarchy,applies role delegation and active time frame constraints,and elaborates this model combining with database design.Finally,expounds several issues,including algorithm to obtain user permissions,design of user group and so on.Practice in project indicates that this model provides flexible and secure access control services.
