METHOD OF DATA BLOCK ENCRYPTION

摘要

The proposed method of block encryption of data for computer processing is distinctive by that the data encryption key and the replacing data blocks are additionally cyclically coded by using the current values of bits that are present in accumulatorregisters corresponding to the left and right data half-blocks. In additional coding of the encryption key and the replacing data blocks, the data on the coding time are used as the initial data for the left and right data half-blocks. On completing the last 16th coding cycle, the data that are present in the accumulator registers are added by modulo 2.
