Onion Routing is a connection-oriented anonymizing
communication service. Users choose a source-routed path
through a set of nodes, and negotiate a "virtual circuit"
through the network, in which each node knows its predecessor
and successor, but no others. Traffic flowing down the circuit
is unwrapped by a symmetric key at each node, which reveals the
downstream node.
