An Administrative Model for Spatio-Temporal Role Based Access Control
In the present computing environment, access control decisions are often based on contextual information like the location of users and objects as well as the time of making an access request. Several variants of Role based Access Control (RBAC) have recently been proposed that support spatio-temporal policy specifications. However, unlike the administrative models available for RBAC, there is ...
متن کاملA context-sensitive dynamic role-based access control model for pervasive computing environments
Resources and services are accessible in pervasive computing environments from anywhere and at any time. Also, due to ever-changing nature of such environments, the identity of users is unknown. However, users must be able to access the required resources based on their contexts. These and other similar complexities necessitate dynamic and context-aware access control models for such environmen...
متن کاملA semantic-aware role-based access control model for pervasive computing environments
Access control in open and dynamic Pervasive Computing Environments (PCEs) is a very complex mechanism and encompasses various new requirements. In fact, in such environments, context information should be used in access control decision process; however, it is not applicable to gather all context information completely and accurately all the time. Thus, a suitable access control model for PCEs...
متن کاملA Spatio-temporal Role-Based Access Control Model
With the growing advancement of pervasive computing technologies, we are moving towards an era where spatio-temporal information will be necessary for access control. The use of such information can be used for enhancing the security of an application, and it can also be exploited to launch attacks. For critical applications, a formal model for spatio-temporal-based access control is needed tha...
متن کاملA Generalized Temporal and Spatial Role-Based Access Control Model
Securing access to data, applied to mobile service applications with temporal and spatial controlling, requires constructing innovative definitions with temporal and spatial limitations for an access-control system. To cope with the temporal and spatial requirements, we propose a generalized Temporal and Spatial RBAC (TSRBAC) model. In the TSRBAC model, temporal-period and spatial-location base...
