THE TCP-CONNECTIONS PROCESSING MODEL FOR STEGANOGRAPHIC DATA TRANSFER IN INFORMATION TELECOMMUNICATION NETWORKS

Ihor V. Ruban, Anton О. Smirnov

Abstract


The model of TCP-connections processing for steganographic data transfer in informationtelecommunication networks has been proposed in this article. The requirements for the modification of the TCP for correct working of the steganographic system has been defined. The functioning of steganographic system when forming and sending of steganographic containers, receiving and extracting of messages has been considered in details. The notions of informative and uninformative values, which calculated during of search of correlations the symbols of open-text (the payload of TCP) with the symbols of the message has been introduced. The model includes blind marking, the implementation of which corresponds to the end of the process of sending (receiving) messages. Justified the lack of time delays in the functioning of the modified TCP relative to its standard version

Keywords


network steganography; steganographic container; initial sequence number.
