Спосіб шифрування даних на основі трьох несумісних груп операцій

Abstract

A method for data encoding based on three incompatible groups of operations consists in the following: a bit string of clear text is divided into n-bits blocks each of which is set one by one to a data storage device. Data from output of the data storage device and data of corresponding subkeyfrom output of a private key storage device of every cycle is entered to input of conversion function which is result of modulo multiplication of data and a first component of sybkey , modulo is a second component of subkey. Function is realised with help of a modulo multiplication unit. Data encoding is performed within L cycles, first and second components of subkey comprise by two coefficients, , which are generated together with the private key and on a keys expansion base beginning from an initial private key and set to the private key storage device. Subkey and input data block is supplied to inputs of modulo 2n adder.
