“The Good, The Bad and The Ugly”: Evaluation of Wi-Fi Steganography

Abstract

-In this paper we propose a new method for the evaluation of network steganography algorithms based on the new concept of "the moving observer". We considered three levels of undetectability named: "good", "bad", and "ugly". To illustrate this method we chose Wi-Fi steganography as a solid family of information hiding protocols. We present the state of the art in this area covering well-known hiding techniques for 802.11 networks. "The moving observer" approach could help not only in the evaluation of steganographic algorithms, but also might be a starting point for a new detection system of network steganography. The concept of a new detection system, called MoveSteg, is explained in detail.

A Wireless Covert Channel Based on Constellation Shaping Modulation

“…The generation mode of these additional constellation points can be controlled by a shared secret key. However, when the detector is near the sender, the regularity of dirty constellation may result in the poor resistance to some statistical detection [17].…”

SocialStegDisc: Application of steganography in social networks to create a file system

“…The research shows that Facebook algorithms are efficient in the detection of steganography known so far, in particular for hidden information of greater size. In [11], a way of evaluation of network steganography techniques was proposed in three categories of undetectability: good, bad and ugly. The presented classification manner may be applied to other steganographic methods.…”

MoveSteg: A Method of Network Steganography Detection

“…As it has been stated before, this transformation is a result of paths traced by the OSPF routing protocol. The nodes collecting data on packet delays will be nodes number 1,6,7,3,9,15,21,20,19,18,34,28,29 (the selected nodes create three "walls" between node 0 and 35 in the topology diagram). LACK will be the steganographic method used.…”
