Access Control Framework for Mobile Terminal Systems
移动终端系统的访问控制框架

With popularity of mobile computing,security issues of mobile terminals recently became a hot research area. Traditional access control technologies can effectively resolve confidentiality and integrity problems of information,but do not pay enough consideration to availability. Compared with personal computers,mobile terminals are easier under Denial of Service attacks by exhausting system resource. In this article,we provided an access control framework for mobile terminals. Extending DTE mechanism to guarantee confidentiality and integrity of information,the framework allows key applications to reserve dynamic resource(such as CPU time and physical memory pages). Managed and scheduled by mobile terminals,reserved resource can be used to avoid resource conflict between key applications and others,which improve response and availability of mobile terminals.
