A Context-Aware Access Control Model for Pervasive Computing in Enterprise Environments

摘要

With the enterprise applications being integrated into the pervasive computing environment, the traditional access control models based on the identity of the user and object have not been suitable to the new requirements of dynamic access authorization to enterprise resources. In this paper, we integrate business and pervasive computing requirements in a single model by extending the Task-Role Based Access model to provide dynamic context-aware access control for pervasive computing in enterprise environments. Unlike traditional approaches for access control, access decisions in will depend on the combination of the required credentials of users, their working environment and context of tasks. It provides a simple and efficient solution to integrate the business applications such as workflow systems into pervasive computing environment.
