An Access Control System for Ubiquitous Computing based on Context Awareness

ABSTRACT It is important to manage access control for secure ubiquitous applications. In this paper, we present an access-control system for executing policy file which includes access control rules. We implemented Context-aware Access Control Manager(CACM) based on Java Context-Awareness Framework(JCAF) which provides infrastructure and API for creating context-aware applications. CACM controls accesses to method call based on the access control rules in the policy file. We also implemented a support tool to help programmers modify incorrect access control rules using static analysis information, and a simulator for simulating ubiquitous applications. We describe simulation results for several ubiquitous applications.Keyword:Access Control, Policy Description Language, Policy File, Context Awareness, JCAF, CACM 1. 서 론 1) 무선 네트워크와 모바일 기기들의 발전과 더불어 이를 통한 다양한 자원 접근이 가능해짐에 따라 안전한 유비쿼터스 응용프로그램을 위한 자원 접근 제어는 필수적이라 할 수 있다. 본 연구는 상황 인식 기술을 기반으로, 실생활에서 발생할 수 있는 다양한 상황들을 반영하여 정확하면서도 유연하게 접근 제어함을 목적으로 한다. 이를 위해 본 논문에서는 프로
