ITR: Mechanisms for Securing Emerging Applications

点击翻译按钮获取中文摘要

As computers become pervasive in the home and community, new applicationswill emerge that will make daily living easier by automating or assisting in a variety of human activities. Suchapplications will be information rich and they will create and manipulatesensitive information about the activities of their users, and the environment in which they live and work. At the Georgia Institute of Technology, an information rich "Aware Home'' hasbeen built to explore many such applications. Clearly, it is importantthat such applications be secured if they are to be deployed successfully.This project will undertake a range of research activities tosecure future applications. These include new security policies for such applications, and intuitive and flexible access control models. A variety of automatic user identification techniques will also be investigated to authenticate sourcesof requests without requiring burdensome participation from the users making the requests. New notions of integrity for information accessed from outside sources will be developed. The authorization, authentication and integrity mechanisms will be used to build security servicesfor emerging applications. The use of formal models will be explored to study important properties of the new security policies and access control models.
