We present an infrastructure for flexible and secure access to a group of distributed services in a nomadic computing environment, wherein users access local services from their mobile, wirelessly connected devices. We describe a secure hand-off' protocol, which allows a user to register with a single service that hands off' authorization to access a subset of the services. Our protocol helps maintain the user's privacy. It allows the services (which may be implemented on simple appliances) and the user's mobile device to have modest resources: services do not have to be online to any party except the user's device and the storage and communication requirements are minimal. In addition to the hand-off protocol, the paper presents a model for authorization hand-off and describes related research and technologies.
