RBAC Standard Rationale: Comments on "A Critique of the ANSI Standard on Role-Based Access Control"
IEEE Security & Privacy Magazine, 2007"For original paper see Ninghui Li et al., vol. 5, no. 6, p.41, (2007)". Some notion of roles for access control predates the research papers cited by the authors by at least a decade. Our work was designed to formalize RBAC and add features (such as hierarchies and constraints) to make it more useful to software developers and administrators ...

Task-Role Based Access Control (T-RBAC): An Improved Access Control Model for Enterprise Environment
2000Companies today manage business information with computer systems and many users access it for their job functions. Companies need security mechanisms to effectively protect important information. Moreover they need to minimize the interruptions from security mechanisms that cause delays in the execution of business activities.

We address the User Authorization Query problem (UAQ) in Role-Based Access Control (RBAC) which relates to sessions that a user creates to exercise permissions. Prior work has shown that UAQ is intractable ( NP -hard). We give a precise formulation of UAQ as a joint optimization problem, and observe that in general, UAQ remains in NP .

2019 IEEE International Conference on Consumer Electronics - Taiwan (ICCE-TW), 2019
Recently there have been many emerging innovated Blockchain applications in various sectors including healthcare. In this paper, we propose a role-based access control system, namely, RBAC-HDE, which harnesses the powerful features of Blockchain such as immutability and decentralization, in order to facilitate secure data exchange for healthcare.

2011 IEEE Symposium on Computers and Communications (ISCC), 2011
The ever-increasing use of information systems and networks in every aspect of our lives has made possible the transfer of data to a wide range of different users and applications. In recent years, several architectures and models have been proposed in order to limit access to resources and ensure that data are available only to authorized users ...
