During operation, each client device will be provided with a list of addresses for all nodes within a network. The addresses for all nodes will be unique to a particular client device such that {address(node 1), address(node 2), . . . address(node n)} for a first client does not equal {address(node 1), address(node 2), . . . address(node n)} for a second client. Each client's address for a particular node will preferably only be known by the client and a naming server. When sending a message to a destination node, a client device will create a source route consisting of the unique addresses. Because each client's address for a particular node will only be known to itself and the naming server, anyone who intercepts the route will not know what nodes along the route are used for routing the message.
