<p>: On the transmitting side, a signature corresponding to a document to be transmitted is generated using a random number and the document as variables and on the basis of a congruent polynomial of second or higher degree with respect to the random number, secret key information and public key information produced based on the secret key information. The signature and the document are transmitted in digital form. On the receiving side, the congruent polynomial is operated using the received signature and document in place of the random number and the document employed on the transmitting side, and the validity of the received signature and document is verified on the basis of the result of the operation and the public key information.</p> |
