RBAC-Based Access Control for Privacy Protection in Pervasive Environments

摘要

Pervasive environment is a post-desktop model of human-computer interaction in which information processing has been thoroughly integrated into everyday object and activities. In there environment access control is a critical issue, with many aspects relating to the establishment, authorization and enforcement of policies that protect the resources from adversaries. Recently, many researches have been worked methods that have access to resources in ubiquitous applications. However they are inadequate to meet the requirement for privacy safeguard and dynamic changes. In this paper we propose how to protect sensitive data and present extended Role Based Access Control (RBAC) that respond to all the requirements for privacy control. We also show how proposed model preserves safety properties in spite of dynamic changes to access control permission.
