ALGORITHM OF CRYPTOGRAPHIC TRANSFORMATION OF PAYLOAD AND KEY INFORMATION BASED ON VERNAM CIPHER AND COMPOSITE CIPHER

Tarasenko Sergey Sergeevich  (employee, Academy of FSO of Russia, Orel )

This paper presents an algorithm for cryptographic transformation of the payload and key information based on the Vernam cipher and a composite cipher. The proposed algorithm implements the division of the key distributed between the parties into two components. The first component has the resistance to cryptanalysis inherent in data encrypted using the Vernam cipher, and the second one has the resistance characteristic of the fundamental principles of ensuring durability – random scattering and random mixing. The cryptographic strength of the first component is much greater than the strength of the second. Thus, the durability of the data encrypted using the proposed algorithm will be no less than the durability of the data encrypted using random scattering and mixing.

Keywords:Vernam cipher, composite cipher, cryptographic strength, cryptanalysis, encryption.
