As
computers become pervasive in the home and community, new applications will
emerge that will make daily living easier by automating or assisting in a variety of human
activities. Such applications will be information rich and they will create and
manipulate sensitive 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'' has been built to explore
many such applications. Clearly, it is important that such applications be
secured if they are to be deployed successfully. This project will undertake a
range of research activities to secure 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 sources
of 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 services for emerging
applications. The use of formal models will be explored to study important properties
of the new security policies and access
control models.
