Secure smart homes using Jini and UIUC SESAME

We discuss our approach to constructing a dynamic and secure smart home environment and tackling the challenges associated with it. We envision a smart home as an active environment populated with smart, dynamically configurable consumer devices capable of interacting with humans and other smart devices. In such a dynamic and active environment, there is a great need for an agile, lightweight, distributed security mechanism. This security mechanism needs to be programmable and able to evolve as rapidly as the environment itself. Yet, this mechanism should be able to adapt to environments with scarce resources. We present Tiny SESAME to meet these challenges while utilizing Jini/sup TM/ technology from Sun Microsystems to handle the common parts of distributed devices. Tiny SESAME is a lightweight component-based, Java-implementation of a subset of SESAME. SESAME is an extension to Kerberos that supports public key technologies, access control, and delegation of access rights. We discuss our Tiny SESAME and how it could be integrated with handheld and consumer devices.
