ABSTRACT:
A packet flow side channel encoder and decoder embeds and extracts a side channel communication in an overt communication data stream transmitted over a network. The encoder selects more than one group of related packets being transmitted on the network, relates a packet of one group to a packet of another group to form a pair of packets; and delays the timing of at least one packet from each pair of packets The decoder determines inter-packet delays that are the difference in timing between two packets in a pair of packets; determines at least one inter-packet delay difference between two or more determined inter-packet delays; and extracts a bit using the at least one interpacket delay difference.
