FIELD: information technology.
SUBSTANCE: first and second data are pre-entered into first and second data processing units, respectively, and a feature of the object is additionally entered into the second data processing unit. A first bit sequence is then generated in the first data processing unit and then transmitted to the second data processing unit, in which there is generation of a second bit sequence from the first bit sequence, as well as second data and the feature of the object through a first conversion algorithm and then transmitted to the first data processing unit in which there is generation of an authentication result for the second data processing unit from the first and second bit sequences and first data through a second conversion algorithm. Further, a third bit sequence is generated in the first data processing unit through a third conversion algorithm and a fourth bit sequence is generated and the bit sequences are transmitted to the second data processing unit.
EFFECT: higher cryptographic security and broader functional capabilities.
