  1. CS 6204 Usable SecurityFall 2009 • Usable Security and Mobility • Project Overview • August 27, 2009

  2. Challenges • What is usable security in a dynamic, mobile, and multi-user environment? • How do we maintain usable security in an ever changing environment? • Possible research topics: • What is a domain or application specific knowledge and how to capture it? • What services/functionalities should be provided? • What are representative scenarios of use? • How to model and handle possibly conflicting users’ security preferences and policies? • How to measure quality of usable security (QoUS)? • How to design and implement a usable security testbed?

  3. Design and Development • Semantic web and related standards (WSDL, OWL, RDF, ...). • Domain specific knowledge and ontologies (Protege). • Policy specification, enforcement and integration (Protune). • Ubiquitous access through web services (SOA and REST). • User interfaces and metaphors (Google Earth).

  4. Case Study: LUMENHAUS • See http://lumenhaus.com. • “LUMENHAUS is Virginia Tech’s 2009 entry to the U.S. Department of Energy Solar Decathlon competition. LUMENHAUS delivers a brighter way to live, literally and figuratively.” • LUMENHAUS is highly automated. • There are many sensors andcontrols available thus providing an “enriched”space, a place, where social interactions among users take place. • The house can be used in many contexts, such as residence, office, store, classroom, etc. • The house can be a part of the larger place that includes the surrounding area and other buildings.
