Design And Implementation For The Enterprise Work Flow Rights Management System Which Based On RBAC Model

With the extensive application of Internet, role-based access control (Role Based Access Control, referred to RBAC) has become the current computer science a very active area of research,RBAC technology is becoming a safe and reliable system of application of an important part of building a sound RBAC Model and design RBAC model based on a reasonable application of the framework is of great significance.First,this aticle introduces several typical role-based access control model,and these types of access control model for analysis and comparison. Then, builds a model based on the improved model SARBAC is call CRBAC model. CRBAC model is the model which based on SARBAC model and make use of ARBAC02 model of the ideological and organizational structure to improve SARBAC model, Mainly the model resolve the following issues: 1.the problem of the role-level manage complex. 2. the problem of the role-level dynamic change not flexible. 3. the problem of the role assign too many steps. 4.the problem of the user-role in the distribution of redundancy. 5.the problem of segregation of duties. 6.the problem of unreasonable authority flows.Finally, this aticle uses CRBAC model thought,combines the enterprise workflow-model, designs and implements the enterprise workflow rights management system, includes the using of CRBAC model, the design for the core framework,the introduce for the mechanism of the access grant and control.
