Many distributed peer-to-peer networks require a discovery mechanism to learn the locations of, and services offered by, participating peers. The problem becomes more complicated when the services reside on a plaintext (trusted) network and communications occur over a cipher-text (untrusted) network. This paper describes the discovery problem where a large number of peers must be capable of both securely registering their location and services with the network, and securely querying network participants to locate peers and/or services. The targeted network environment includes up to 10 nodes that may be fixed or mobile. These nodes may have limited bandwidth or intermittent availability. Also, the network end-to-end latency may be large.
