Proceedings of the 19th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2011 As mobile computing devices are becoming increasingly dominant in enterprise and government organizations, the need for fine-grained access control in these environments continues to grow. Specifically, advanced forms of access control can be deployed to ensure authorized users can access sensitive resources only when in trusted locations.

Extended privilege inheritance in RBAC [PDF]
Proceedings of the 2nd ACM symposium on Information, computer and communications security, 2007 In existing RBAC literature, administrative privileges are inherited just like ordinary user privileges. We argue that from a security viewpoint this is too restrictive, and we believe that a more flexible approach can be very useful in practice. We define an ordering on the set of administrative privileges, enabling us to extend the standard privilege

Migrating from RBAC to temporal RBAC
IET Information Security, 2017 The last two decades have witnessed an emergence of role-based access control (RBAC) as the de facto standard for access control. However, for organisations already having a deployed RBAC system, in many cases it may become necessary to associate a temporal dimension with the existing access control policies due to changing organisational requirements.

Authorization recycling in RBAC systems [PDF]
Proceedings of the 13th ACM symposium on Access control models and technologies, 2008 As distributed applications increase in size and complexity, traditional authorization mechanisms based on a single policy decision point are increasingly fragile because this decision point represents a single point of failure and a performance bottleneck. Authorization recycling is one technique that has been used to address these challenges.

R-PEKS: RBAC Enabled PEKS for Secure Access of Cloud Data [PDF]
, 2019 In the recent past, few works have been done by combining attribute-based access control with multi-user PEKS, i.e., public key encryption with keyword search.

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.
