We describe an approach to building security servicesfor context-aware environments. Specifically, we focus onthe design of security services that incorporate the use ofsecurity-relevant "context" to provide flexible access controland policy enforcement. We previously presented a generalizedaccess control model that makes significant use ofcontextual information in policy definition. This documentprovides a concrete realization of such a model by presentinga system-level service architecture, as well as early implementationexperience with the framework. Through ourcontext-aware security services, our system architecture offersenhanced authentication services, more flexible accesscontrol and a security subsystem that can adapt itself basedon current conditions in the environment. We discuss ourarchitecture and implementation and show how it can beused to secure several sample applications.
