METHOD FOR GENERATION AND VERIFICATION OF COLLECTIVE ELECTRONIC DIGITAL SIGNATURE THAT CERTIFIES ELECTRONIC DOCUMENT Russian patent published in 2010 - IPC H04L9/14 G06K5/00

Abstract RU 2402880 C2

FIELD: information technologies.

SUBSTANCE: method for generation and verification of electronic digital signature (EDS) includes the following sequence of actions: combination of n≥2 secret keys is generated in the form of multidigit binary numbers (MBN) k₁, k₂,…,k_n, using secret keys, n open keys P₁, P₂, …, P_n are generated, at least one electronic document presented by MBN is received, depending on received electronic document and on value of at least two secret keys, electronic digital sinature Q is generated in the form of two or more MBN, collective open key is generated depending on T open keys where a₁, a₂,…,a_m are natural numbers, 2≤m≤n, a_j≤n and j = 1, 2,…,m, the first A and second B verification MBN are generated, besides at least one of verification MBN is generated depending on collective open key. MBN A and B are compared. If their parametres coincide, conclusion on authenticity of electronic digital signature is made.

EFFECT: reduced size of collective electronic digital signature without reduction in its level of resistance.
