FIELD: information technology.
SUBSTANCE: invention relates to information processing technology and communication technology. Information processing device, comprising generating module numbers, configured to generate numbers, used in coefficients of members of a pair of polynomials F = (f1, …, fm) of multiple orders from several variables, using preset function on basis of information shared by objects, performing algorithm of authentication with open key or algorithm of digital signature, which applies open key, containing above pair of polynomials F multiple orders from several variables and module purpose configured to assign numbers generated by module for generating numbers, coefficients of polynomials of multiple orders from several variables, components of which is above pair of polynomials F multiple orders from several variables.
EFFECT: technical result is provision of efficient security of electronic documents.
