ELECTRONIC SIGNATURE METHOD WITH A SELL-INSPECTION CHARACTERISTIC

摘要

The present invention relates to a digital electronic signature method based on personal identification information having self-certification characteristics. The present invention solves a stability problem based on a high residual filter problem and a discrete algebra problem, and the center knows each user's secret key. A first step (21) of initializing a coefficient to provide a new digital signature method based on self-identifying personal identification information which cannot be verified and which is not required by the authenticator; A second step 22 of selecting the personal identification information I as a public key; A third step (23) of calculating verification information (i, x); A fourth step (24 to 27) for selecting a random number r and calculating a signature intermediate value v, a hash function result e and signature information z for plain text; And a fifth step (28, 29) in which the verifier calculates the hash function and then verifies the verification function after calculating the verification median value (v). There is an effect that can not meet the minimum recognition conditions.
