Abstract
Network steganography has been a well-known covert data channeling
method for over three decades. The basic set of techniques and implementation
tools have not changed significantly since their introduction in the early
1980’s. In this paper, we review the predominant methods of classical network
steganography, describing the detailed operations and resultant challenges
involved in embedding data in the network transport domain. We also consider
the various cyber threat vectors of network steganography and point out the
major differences between classical network steganographyand the widely known
end-point multimedia embedding techniques, which focus exclusively on static data
modification for data hiding. We then challenge the security community by
introducing an entirely new network data hiding methodology, whichwe refer to
as real-time network data steganography. Finally, we provide the groundwork for
this fundamental change of covert network data embedding by introducing a
system-level implementation for real-time network data operations that will
open the path for even further advances in computer network security.
