ABSTRACT:
A communications network circuit through which data packets are flowing is identified by detecting a first message data packet inserted into the data packet flow by a user, and determining an endpoint destination address of the detected data packet. The circuit using the endpoint destination address is identified and a second message data packet containing the circuit identification information is sent to the destination address. A covert timing channel may be created, and one or more data packets containing circuit identification information may be sent through the covert channel.
