FIELD: computer engineering.
SUBSTANCE: invention relates to computer engineering and can be used for parallel implementation systems Boolean functions with a function of control computation errors in means of cryptographic information protection. Device provides calculation system of Boolean functions, presented in a numerical form, by applying excessive code modular and additionally contains a memory register, a memory unit storing bases system, units for calculating the least non-negative residue number at the bases of the system, multipliers, multi-bed adders, a decision system comparisons with one unknown, comparison unit, unit of the operator masking.
EFFECT: technical result is expansion of device functional capabilities by enabling accurate calculation of binary pseudorandom sequences, identical pseudo-random sequences obtained by means of classical generators on linear recurrent shift registers.
