StegBlocks: ensuring perfect undetectability of network steganography
This addresses the challenge of secure and covert data transmission for users in network security, though it appears incremental as it builds on existing steganography principles.
The paper tackles the problem of undetectable hidden communication in networks by introducing StegBlocks, a general approach for constructing network steganography methods, and demonstrates the possibility of achieving perfect undetectability based on established steganography rules.
The paper presents StegBlocks, which defines a new concept for performing undetectable hidden communication. StegBlocks is a general approach for constructing methods of network steganography. In StegBlocks, one has to determine objects with defined properties which will be used to transfer hidden messages. The objects are dependent on a specific network protocol (or application) used as a carrier for a given network steganography method. Moreover, the paper presents the approach to perfect undetectability of network steganography, which was developed based on the rules of undetectability for general steganography. The approach to undetectability of network steganography was used to show the possibility of developing perfectly undetectable network steganography methods using the StegBlocks concept.
