a Attribute-based Access Control Model for Web is presented based on the thought of Trust Management.A new type of attribute certificate based on XML is specified for this model and the model adopts a new language to specify the access control policy.The main parts such...
Current access control models such as RBAC and ABAC do not address real-time availability in a scalable way for such scenarios. In this paper we propose a real-time attribute-based access control model that extends the functionality of ABAC by using real-time attributes that reflect the ...
A Model for Attribute Based Role-Role Assignment (ARRA) Administrative Role Based Access Control (ARBAC) models specify how to manage user-role assignments (URA), permission-role assignments (PRA), and role-role assignments (RRA). Many approaches have been proposed in the literature for URA, ....
Role based access control (RBAC) is well known due to its high security and ease in management for permissions. But it also has some deficiencies like role structure complexity and having no dynamic behavior. Attribute based access control (ABAC) is a dynamic access control model that provides ...
