Network Steganography and Network Steganalysis

---

Internet has become part of our everyday life. The endless usage of computer networks makes network security the highest priority in communications. Network steganography is to transmit secret data within user’s normal data transmission without being detected by third parties, which is also called covert channels. Covert channels via network protocols have become a new challenge issue for network security. The huge amount of data transmitted over Internet by using TCP/IP protocols makes it ideal as a carrier in steganography. Attacks based on covert channels become a potential threat to the Internet. In this talk, we will briefly review network protocols and introduce network steganography, and network steganalysis. The information hiding in network protocols and the corresponding countermeasures or network steganalysis will be discussed. Finally, we will present our proposed detection method PRM (Phase Reconstruction Method) to detect covert channels in TCP ISNs and IP IDs.
