Delegation in Role-Based Access Control [PDF]
International Journal of Information Security, 2006 User delegation is a mechanism for assigning access rights available to one user to another user. A delegation can either be a grant or transfer operation. Existing work on delegation in the context of role-based access control models has extensively studied grant delegations, but transfer delegations have largely been ignored.

Fuzzy Role-Based Access Control [PDF]
Information Processing Letters, 2011 RBAC (Role-Based Access Control) is a widely used access control model, which reduces the maintenance cost of classical identity-based access control. However, despite the benefits of RBAC, there are environments in which RBAC can hardly be applied. We present FRBAC (Fuzzy Role-Based Access Control), a generalization of RBAC through fuzzy relations ...

Role-based access control on the web [PDF]
ACM Transactions on Information and System Security, 2001 Current approaches to access control on the Web servers do not scale to enterprise-wide systems because they are mostly based on individual user identities. Hence we were motivated by the need to manage and enforce the strong and efficient RBAC access control technology in large-scale Web environments.

Obligations for Role Based Access Control [PDF]
21st International Conference on Advanced Information Networking and Applications Workshops (AINAW'07), 2007 Role based access control has been widely researched in security critical systems. Conventional role based access control is a passive model, which makes authorization decisions on requests, and the authorization decisions contain only information about whether the corresponding requests are authorised or denied.

Role-Based Access Control in Retrospect [PDF]
Computer, 2012 A review of the state of the art of role-based access control can help practitioners assess RBAC's applicability to their organization and indicates where more research is needed to improve the RBAC model.

Role-Based Access control mechanisms [PDF]
2014 IEEE Symposium on Computers and Communications (ISCC), 2014 Most of the security threats in relational database applications have their source in client-side systems when they issue requests formalized by Create, Read, Update and Delete (CRUD) expressions. If tools such as ODBC and JDBC are used to develop business logics, then there is another source of threats.

RBAC-SC: Role-Based Access Control Using Smart Contract
IEEE Access, 2018 The role-based access control (RBAC) framework is a mechanism that describes the access control principle. As a common interaction, an organization provides a service to a user who owns a certain role that was issued by a different organization.
