FIELD: electronic communications engineering, namely, engineering of cryptographic devices and methods for checking electronic digital signature.
SUBSTANCE: method for checking electronic digital signature contains actions in following order: receipt of electronic document in form of multi-bit binary number H, open key in form of first g-bit and second f-bit binary number n and α and electronic digital signature in form of multi-bit binary number S; generation of checking multi-bit binary number B by involution of electronic digital signature to power H by module n; comparison of binary numbers B and α. In case of match, deduction about authenticity of electronic digital signature is done.
EFFECT: decreased probability of unsanctioned generation of electronic digital signature (false confirmation of authenticity of electronic digital signature) in electronic digital signature systems.
