Proposed models for spatially-aware extensions of role-based access control (RBAC) combine the administrative and security advantages of RBAC with the dynamic nature of mobile and...
This paper presents an approach that uses special purpose RBAC constraints to base certain access control decisions on context information. In our approach a context constraint is...
—Constraints are an important part of role-based access control policies. The safety or security of a system is maintained by enforcing constraints that are specified in the pol...
Pervasive computing environments have created a requirement for spatial- and temporal-aware access control systems. Although temporal, spatial and spatio-temporal role-based acces...
Emerging models for context-aware role-based access control pose challenging requirements over policy administration. In this paper we address the issues raised by the decentraliz...
