The User Information Architecture, or UIA, is a peer-to-peer
connectivity architecture that provides users a simple, intuitive, and secure
way to share information and services between personal devices by assigning ad
hoc names that act like “virtual cables.” Users assign names by “introducing”
devices to each other on a common network. Unlike the ephemeral names used in
rendezvous schemes such as Apple Bonjour, however, UIA names persist and
remain securely bound to the global cryptographic identities of their targets
as devices migrate.
