Abstract

In this thesis, we develop network information hiding methods which can be utilized to transmit external information between two network end-systems as stealthy as possible. Here, we propose three network information hiding methods namely, Packet Payload Byte Parity Based Steganography, Alternative Packet Payload Bit Parity Based Steganography and finally, the IP Identification Based Steganographic method. In the first and second methods, we exploit the parity of the payload to encode external information. We examine and analyze the packet lengths of normal traffic to show that the methods can cope with traffic anomaly detection methods and do not introduce noticeable overhead. Results suggest that the proposed methods achieve high undetectability at 1 bit per packet of channel capacity. On the other hand, we propose to utilize the IP identification field to establish steganographic communication in operating systems which manifest randomness in their IP identification generation.
