Non-interactive Digital Signature Method Based on Personal Identification Information with Self-Authentication Feature

摘要

The present invention relates to a digital digital signature method based on personally identifiable information having self-authentication characteristics, solves a stability problem based on a high-order surplus problem and a discrete algebra problem, A first step (21) of initializing a coefficient to provide a new digital signature method based on self-authenticating personally identifiable information which is not available and does not require an authenticator; A second step (22) of selecting the individual 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 the random number (r) to calculate the signature intermediate value (v), the hash function result (e) and the signature information (z) for the plain text; And the verifier includes a fifth step (28,29) of calculating and verifying the hash function after calculating the verification intermediate value (v) so that the verifier verifies the signature statement completely and any user generates a signature statement And the minimum recognition condition can be satisfied.
