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 کاملConditional Privacy-Aware Role Based Access Control
Privacy is considered critical for all organizations needing to manage individual related information. As such, there is an increasing need for access control models which can adequately support the specification and enforcement of privacy policies. In this paper, we propose a model, referred to as Conditional Privacy-aware Role Based Access Control (P-RBAC), which supports expressive condition...
متن کاملRisk-Aware Role-Based Access Control
The increasing need to share information in dynamic environments has created a requirement for risk-aware access control systems. The standard RBAC model is designed to operate in a relatively stable, closed environment and does not include any support for risk. In this paper, we explore a number of ways in which the RBAC model can be extended to incorporate notions of risk. In particular, we d...
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 کاملLRBAC: A Location-Aware Role-Based Access Control Model
With the growing use of wireless networks and mobile devices, we are moving towards an era where location information will be necessary for access control. The use of location 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 location-based access control is needed that increases th...
