New Paper accepted: Inter-protocol Steganography for Real-time Services and Its Detection Using Traffic Coloring Approach

We got a new paper accepted at the 42th IEEE Conference on Local Computer Networks (LCN), taking place during October in Singapore:

F. Lehner, W. Mazurczyk, J. Keller, S. Wendzel: Inter-protocol Steganography for Real-time Services And Its Detection Using Traffic Coloring Approach, in Proc. 42th IEEE Conf. Local Computer Networks (LCN), IEEE, 2017 (in press).

Abstract: Due to improvements in defensive systems, network threats are becoming increasingly sophisticated and complex as cybercriminals are using various methods to cloak their actions. This, among others, includes the usage of network steganography which is utilized e.g. to hide the communication between the infected host and malicious control server by embedding commands into an innocent-looking traffic. Currently, a new subtype of such methods emerged called inter-protocol steganography which utilize relationships between two or more overt protocols in order to hide data. In this paper, first, we present new inter-protocol hiding techniques which are suitable for real-time services. Then, we introduce and present preliminary results of a novel steganography detection approach which relies on the network traffic coloring.
