Efficient and Flexible Role-Based Access Control (EFRBAC) Mechanism for Cloud [PDF]
EAI Endorsed Transactions on Scalable Information Systems, 2020 The cloud reduces the user’s burden to many folds. But cloud providers and cloud users with dynamic relationship, are in distinct security domains. Amongst various challenges with cloud, the crucial one is to detect and protect the user’s data from ...

Cryptographic Role-Based Access Control, Reconsidered [PDF]
, 2022 In this paper, we follow the line of existing study on cryptographic enforcement of Role-Based Access Control (RBAC). Inspired by the study of the relation between the existing security definitions for such system, we identify two different types of attacks which cannot be captured by the existing ones.

Self-Adaptive Role-Based Access Control for Business Processes [PDF]
International Symposium on Software Engineering for Adaptive and Self-Managing Systems, 2017 © 2017 IEEE. We present an approach for dynamically reconfiguring the role-based access control (RBAC) of information systems running business processes, to protect them against insider threats. The new approach uses business process execution traces and

Lambda-RBAC: Programming with Role-Based Access Control [PDF]
Logical Methods in Computer Science, 2008 We study mechanisms that permit program components to express role constraints on clients, focusing on programmatic security mechanisms, which permit access controls to be expressed, in situ, as part of the code realizing basic functionality.

Role-based access control in DCOM [PDF]
Journal of Systems Architecture, 2000 The explosive growth of the Web, the increasing popularity of PCs and the advances in high-speed network access have brought distributed computing into the mainstream. To simplify network programming and to realize component-based software architecture, distributed object models have emerged as standards.

Role-Based Access Controls [PDF]
15th National Computer Security Conference, Baltimore, MD. October
13-16, 1992, 2009 While Mandatory Access Controls (MAC) are appropriate for multilevel secure military applications, Discretionary Access Controls (DAC) are often perceived as meeting the security processing needs of industry and civilian government. This paper argues that reliance on DAC as the principal method of access control is unfounded and inappropriate for many ...

Permission-Based Separation of Duty in Dynamic Role-Based Access Control Model [PDF]
Symmetry, 2019 A major development in the field of access control is the dominant role-based access control (RBAC) scheme. The fascination of RBAC lies in its enhanced security along with the concept of roles. In addition, attribute-based access control (ABAC) is added

Security analysis in role-based access control [PDF]
Proceedings of the ninth ACM symposium on Access control models and technologies, 2004 The administration of large role-based access control (RBAC) systems is a challenging problem. In order to administer such systems, decentralization of administration tasks by the use of delegation is an effective approach. While the use of delegation greatly enhances flexibility and scalability, it may reduce the control that an ...
