InCC: Hiding information by Mimicking traffic in network flows

Abstract

This article proposes and implements a light-weight covert channel called InCC, which is designed to produce a undetectable communication channel between systems. This channel, fully transparent to any network analysis, is able to send messages on the same production network without compromising its existence. By using techniques like encryption, address spoofing, signatures and traffic analysis, the channel is able to hide the flows on the network without compromising the source and destination.
