Abstract
In this article, we address the global problem of improving the quality of cryptographic trans-forming information. There were revealed contradictions between the approaches to the development of encryption algorithms for information security systems and encoding algorithms for information protection in computer systems and networks. One of the variants to solve this problem is creation a theory of cryptographic encoding. This work will explain the origins of researching the information encoding processes under the control of cryptographic primitives. The encryption algorithms' synthesis and analysis through the prism of discrete devices synthesis and analysis allow us to consider the cryptographic algorithms' classification issues in a different way, to determine possible directions for developing the new crypto algorithms, and to improve existing crypto algorithms. The correlations between symmetric and asymmetric ciphers are being analyzed. A new approach to the construction of asymmetric stream ciphers is proposed. The methods for increasing the length of the block of information and the length of the key for both new and already known encryption algorithms, as well as options for their implementation, are presented. The given examples of encryption algorithms demonstrate new opportunities for improving the computer cryptography systems and the information security cryptographic systems based on applying the new knowledge being obtained in the process of constructing a cryptographic encoding theory.
