Time-constraint Access Control in Pervasive Computing Environments

چکیده
This paper presents a novel access control model named PC-TRBAC (Time-constraint Role-based access control for Pervasive Computing). We give a detail analysis of the access control characteristics in the pervasive computing environments and the overview of the traditional access control model. In order to adapt to the pervasive computing, we add some time constraints into our new access control. Some new time constraints including active time span, active time length, activation time interval, average active duration and entity dependency duration were proposed. At last, we give the framework of our new access control model, and the component definitions are also proposed.

A 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...

Mandatory access control models have traditionally been employed as a robust security mechanism in multilevel security environments such as military domains. In traditional mandatory models, the security classes associated with entities are context-insensitive. However, context-sensitivity of security classes and flexibility of access control mechanisms may be required especially in pervasive c...

متن کاملAn Access Control Framework for Pervasive Computing Environments
The explosive evolution of pervasive computing environments presents several new challenges such as smart spaces, invisibility, localized scalability, and masking uneven conditioning. One of the key challenges in such environments is how to manage security and access control. A suitable approach for managing access control in pervasive computing environments should consider different features o...
