Abstract

A certificate issuance support system includes a certificate application device in a first organization for applying to an authentication station for issuance of an OV certificate; and an existence assurance device in a second organization for guaranteeing the existence of the first organization. The existence assurance device imparts a first signature to first information for guaranteeing the existence of the first organization in response to a request from a terminal used by a member of the first organization, transmits the first information imparted with the first signature is to the certificate application device, and verifies a second signature generated by the certificate application device and imparted to second information for guaranteeing affiliation of the member with the authentication station. The certificate application device transmits the first information with the first signature and the second information with the second signature to the authentication station to receive the OV certificate.

Claims (19)

1. A certificate issuance support system comprising:

a certificate application device in a first organization for applying to an authentication station for issuance of an OV certificate, the certificate application device including a memory and a processor; and

an existence assurance device included in a second organization for guaranteeing the existence of the first organization, the existence assurance device including a memory and a processor,

wherein the processor of the existence assurance device is configured to

impart a first electronic signature to first information for guaranteeing the existence of the first organization in response to a request from a terminal used by a member of the first organization,

transmit the first information to which the first electronic signature is imparted to the certificate application device, and

verify a second electronic signature, which is generated by the certificate application device and is imparted to second information for guaranteeing affiliation of the member of the first organization in cooperation with the authentication station, and

wherein the processor of the certificate application device transmits the first information to which the first electronic signature is imparted and the second information to which the second electronic signature is imparted to the authentication station to receive the OV certificate issuance.

2. The certificate issuance support system according to claim 1 , wherein the processor of the existence assurance device imparts the first electronic signature to the first information in a case where the member is authenticated.

3. The certificate issuance support system according to claim 1 , wherein the processor of the certificate application device executes transmission of the first information and the second information to the authentication station in addition to a protocol according to an automatic certificate management environment (ACME).

4. A certificate issuance support method executed by a certificate application device in a first organization for applying to an authentication station for issuance of an OV certificate, and an existence assurance device included in a second organization for guaranteeing the existence of the first organization, the method comprising:

having a processor of the existence assurance device execute

imparting a first electronic signature to first information for guaranteeing the existence of the first organization in response to a request from a terminal used by a member of the first organization,

transmitting the first information to which the first electronic signature is imparted to the certificate application device, and

verifying a second electronic signature, which is generated by the certificate application device and is imparted to second information for guaranteeing affiliation of the member of the first organization in cooperation with the authentication station, and

having a processor of the certificate application device transmit the first information to which the first electronic signature is imparted and the second information to which the second electronic signature is imparted to the authentication station to receive the OV certificate issuance.

5. The certificate issuance support method according to claim 4 , wherein the imparting of the first electronic signature includes imparting the first electronic signature to the first information in a case where the member is authenticated.

6. The certificate issuance support method according to claim 4 , wherein the processor of the certificate application device executes transmission of the first information and the second information to the authentication station in addition to a protocol according to an automatic certificate management environment (ACME).

7. A non-transitory computer-readable recording medium having computer-readable instructions stored thereon, which when executed, cause a computer to execute operations executed by the processor of the existence assurance device in the certificate issuance support method according to claim 4 .
