Abstract

Ubiquitous environment that is omnipresent is existent everywhere or seems to be always present. Such an environment is a next generation paradigm in which many invisible computers are integrated into background of our lives. However, it requires more secure technologies to protect privacy because user may access information without time and space restriction. In this paper, we propose the mechanism that a user is able to automatically access to resource by means of context aware on ubiquitous computing environments. For this purpose, we exploit Role-Based Access Control (RBAC) and Mandatory Access Control (MAC) policies, and defines extended context rules.We also provide an advanced security authorization mechanism and show how to securely preserve properties despite of dynamic change of access control privilege.
