摘要：Network steganography has been a well-known covert data channeling method for over three decades. Thebasic set of techniques and implementation tools have not changed significantly since their introduction inthe 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 networktransport domain. We also consider the various cyber threat vectors of network steganography and pointout the major differences between classical network steganographyand the widely known end-pointmultimedia embedding techniques, which focus exclusively on static data modification for data hiding. Wethen 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 thisfundamental change of covert network data embedding by introducing a system-level implementation forreal-time network data operations that will open the path for even further advances in computer networksecurity.
