FIELD: physics, computer equipment.
SUBSTANCE: device of information processing contains the first module of formation that is arranged with the possibility to form data, which will be signed, the second module of formation made with the possibility to form the first values of data digest, which should be signed, and identifiers that are used for identification of data that should be signed, the third module of formation, which is arranged with the possibility to form information of signature on the basis of multiplicity of the first digest values and identifiers obtained from digital document, and the fourth module of formation that is arranged with the possibility to form the first signed digital document on the basis of signature and data that should be signed. Device of verification verifies digital document on the basis of the first signed digital document formed by device of information processing.
EFFECT: higher accuracy of signature verification by verification of digital data content.
