Covert communication is a rapidly expanding field of research with significant impact on the security theater. These communication methods, or “covert channels”, can be applied in a number of ways, including as a mechanism for an attacker to leak data from a monitored system or network. This paper sets out to contribute to this field by introducing a new covert channel which operates over transport layer protocols. The mechanism is flexible, covert, and has the potential to operate at relatively high bandwidth. In addition, this paper proposes a number of encoding schemes which can be used in conjunction with this channel to improve its bandwidth and covertness.
