The Research Of RBAC Model And Implementation Of Its Application Framework

With the wide application of the Internet, currently, Role_Based Access Control has been a quite active research field of the Computer Science, and the techniques of RBAC are becoming the important part of a secure and credible application system. It's of high significance that building a perfect model of Role_Based Access Control and designing an reasonable application framework based on an RBAC Model.The paper first introduces several typical Role_Based Access Control models, at the same time analyses and compares them. Next, the improved model named WARBAC, based on SARBAC model, is put forward. WARBAC model is designed based on the existing SARBAC model, resorting to the conception of the organization of the ARBAC02 model,and upswings the SARBAC model further.On the sake for convenience, we call the mend model as "WARBAC" model. Then, the application framework found on WARBAC model, referring to the access control framework of x.812|ISO 10181,is given,and its designing technology is probed into particularly.mainly including the application system framework based upon WARBAC model , the design concerning tactic, performance function, decision-making function, communication mode and management of access control of WARBAC and the service based on LDAP, etc. At the end of the paper, a realized file management system-UJSFWM, originating from the application framework of WARBAC model,is illustrated The function of the UJSFWM system and the realization of the concerning technology are explained at length in the paper.
