A method of transmitting a covert message over a network from an origin device to a destination device includes using selection a plurality of network paths, network channels, and network tunnels to signal to the destination device symbols. Sequences of the symbols are interpreted by the destination device as values in an n-based number system. The values are decoded by the destination device to obtain the covert message. Some preferred implementations use a binary number system and some use a hexadecimal number system. Some utilize network path selection and incorporate network watermarks, by which the network path that was selected for each received packet is determined. Network paths preferably are differentiated from one another by redirects that are storage servers in an overlay network. Network communications can be opened between the origin device and destination device for continuously communicating packets without signaling symbols when no covert message is being transmitted.
A method of transmitting a covert message over a network from an origin device to a destination device, comprising using selection by the origin device of a plurality of network paths, network channels, and network tunnels to signal to the destination device symbols, wherein sequences of the signaled symbols are interpreted by the destination device as values, wherein the interpreted values represent an encoded message that is then decoded by the destination device to obtain the covert message, and wherein a selected one of the plurality of network paths, network channels, and network tunnels comprises a path comprising a plurality of prime nodes.
A method of transmitting a covert message over a network from an origin device to a destination device, comprising using selection by the origin device of a plurality of network paths, network channels, and network tunnels to signal to the destination device symbols, wherein sequences of the signaled symbols are interpreted by the destination device as values, wherein the interpreted values represent an encoded message that is then decoded by the destination device to obtain the covert message, and wherein a selected one of the plurality of network paths, network channels, and network tunnels comprises a network path comprising a sequence of node identifiers comprising IP addresses and MAC addresses.
An electronic device forming a node of one or more networks and configured to perform a method of transmitting a covert message over a network to a destination device, comprising using selection by the electronic device of a plurality of network paths, network channels, and network tunnels to signal to the destination device symbols, wherein sequences of the signaled symbols are interpreted by the destination device as values, and wherein the interpreted values represent an encoded message that is then decoded by the destination device to obtain the covert message.
