Method of the adaptive multilayer information protection on the basis of steganography and cryptography
Vitalii Lukichov, Yuriy Baryshev, Natalia Kondratenko, Vadim MalinovskyiAn analysis of known solutions to the problem of steganographic and cryptographic methods combining to achieve multilayer information protection is presented. Results of the analysis allowed us to identify trends and prospects for the development of these kink of methods. Based on the results of the analysis, the research task was determined concerning the adaptation of the used cryptographic and steganographic methods in order to achieve the best level of protection, which is needed at critical systems. Metrics were defined, those allowed to choose the best combination of cryptographic and steganographic protection methods parameters. A method of multilayered information protection is presented, which combines cryptographic and steganographic approaches to ensure an increased level of information’s confidentiality and integrity protection. It is proposed to introduce criteria for the selection of cryptographic transformations in such a way that their combination together with steganographic transformations gives the best impact. An instance of the proposed method implementation is given in order to prove the concept. An algorithm has been developed that implements the proposed method of adaptive multilayer information protection. The perspective of further research is determined
