Field: Digital communication (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A method of receiving and processing a covert transmission within a TCP/IP protocol stack, said method comprising:
receiving network traffic at an electrical interface, wherein the network traffic comprises normal network traffic and a datagram, intermingled with the normal network traffic and comprising data for covert delivery at an IP protocol layer, wherein said datagram is artificially manipulated to appear as a non-conforming data transmission at the IP layer by inaccurate description of one or more features of the datagram in a fashion which prevents normal processing through the TCP/IP protocol stack;
intercepting said datagram at a covert interception routine inserted as an extension of at least one of the IP protocol layers;
processing said datagram at a covert processing routine to extract said data for covert delivery; and
subsequently discarding the datagram as a non-conforming data transmission at the IP layer.
