ICAF: A Context-Aware Framework for Access Control
نویسندگان
چکیده
Context-aware systems acquire and integrate multi-faceted knowledge about their environments in order to make decisions. A number of attempts to build frameworks for context-aware systems have been made, but these have not provided adequate support for context-aware access control. In this paper, we present a framework for context-aware access control and its prototype implementation. The framework includes a context model for classifying and capturing access control-oriented contextual information, a situation model for identifying and defining contextual conditions of concern, and a policy model for specifying context-aware access control policies.

A 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 کاملCAMAC: a context-aware mandatory access control model
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 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 Policy Model and Framework for Context-Aware Access Control to Information Resources
In today’s dynamic ICT environments, the ability to control users’ access to information resources and services becomes ever important. On the one hand, it should adapt to the users’ changing needs; on the other hand, it should not be compromised. Therefore, it is essential to have a flexible specification of access control polices, incorporating dynamically changing context information. The ba...
متن کاملAn ontological framework for situation-aware access control of software services
Situation-aware applications need to capture relevant context information and user intention or purpose, to provide situation-specific access to software services. As such, a situation-aware access control approach coupled with purpose-oriented information is of critical importance. However, modelling purpose-oriented situations is a challenging task. Existing modelling approaches for situation...
