Abstract

A certificate issuing support system includes: a certificate application device in a first organization making an application for issuing an EV certificate to a certificate authority; and an existence guarantee device included in a second organization that guarantees existence of the first organization. The existence guarantee device assigns a first electronic signature to first information guaranteeing existence of the first organization in response to a request from a terminal used by a member of the first organization, and verifies a second electronic signature assigned to second information that is generated by the certificate application device and guarantees affiliation of the member to the first organization in cooperation with the certificate authority. The certificate application device assigns a third electronic signature to third information indicating an authority of a person who approves the application for issuing the EV certificate, and transmits the first information to which the first electronic signature is assigned, the second information to which the second electronic signature is assigned, and the third information to which the third electronic signature is assigned to the certificate authority in order to obtain the approval of the issuing of the EV certificate, and thus automatic issuing of the EV certificate is supported.
