Document Type and Number:
WIPO Patent Application WO/2020/017643
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an electronic signature system with which it is possible to reduce burden on a user and to safely perform issuance and registration of an electronic certificate. A terminal device 10 makes an authentication request to a key management server 30. If authentication has been successful, the key management server 30 transmits an authorization code to the terminal device 10. The terminal device 10 sends the authorization code to a certificate issuance server 20. The certificate issuance server 20 sends the authorization code sent from the terminal device 10 to the key management server 30. The key management server 30 sends an access token to the certificate issuance server 20 in exchange for the authorization code. The certificate issuance server 20, by presenting the access token to the key management server 30, obtains a certificate signature request from the key management server 30, and issues an electronic certificate with respect to a public key described in the certificate signature request.
