METHOD FOR ENCODING BINARY INFORMATION AND DEVICE FOR REALIZATION OF METHOD Russian patent published in 2005 - IPC

FIELD: cryptographic transformations.

SUBSTANCE: method includes use of combined procedure for receiving binary digit of encryption gamma in M processing channels and using functional transformation of intermediate result in each of M channels with generated encryption gamma. Device, meant for realization of method, has adder and encryption gamma generator at input and output, including key register, encrypted text and encryption gamma shift registers, block for forming binary digit of encryption gamma and M channels for forming binary result of processing, each of which consists of arithmetical subtraction device, logical adder with formed encryption gamma and major block, while resulting encryption gamma is produced by modulo adding of two channel encryption gammas.

EFFECT: higher level of randomization of generated encrypted text, and also higher speed of operation of encryption algorithm.
