We describe a resource discovery and communication system designed for security and privacy. All objects in the system, e.g., appliances, wearable gadgets, software agents, and users have associated trusted software proxies that either run on the appliance hardware or on a trusted computer. We describe how security and privacy are enforced using two separate protocols: a protocol for secure deviceto-proxy communication, and a protocol for secure proxyto-proxy communication. Using two separate

We detail the device-to-proxy protocol for lightweight wireless devices and the proxy-to-proxy protocol which is based on SPKI/SDSI (Simple Public Key Infrastructure / Simple Distributed Security Infrastructure). A prototype system has been constructed, which allows for secure, yet efficient, access to networked, mobile devices. We present a quantitative evaluation of this system using various metrics.
