FIELD: physics.
SUBSTANCE: device for constructing replacement nodes is proposed, consisting of a mode selection unit, a cryptographic parameters calculating unit, a unit for calculating values of the target vector function, a control unit, a transformation generating unit, a unit for multiplying replacement node to conversion, a random access memory.
EFFECT: construction with a reasonable labour intensity of a large number of affine-non-equivalent replacement nodes with high values of the main cryptographic parameters from random mappings or known nodes.
