Abstract:
1. A server certificate issuing system comprising a registration server controlled by a registration authority to receive a server certificate request transmitted from a Web server, communication server or load balancer via a network and to transmit a certificate signing request file to a certificate issuing authority, a certificate issuing server controlled by the certificate issuing authority to receive the certificate signing request file transmitted from the registration server via a network, to generate a server certificate with a digital signature, and to transmit the generated server certificate to said registration server, and a test certificate issuing server controlled by a test certificate issuing authority which issues a test certificate used for testing to receive a test certificate issuing request transmitted from the registration server via a network and to issue the test certificate, wherein said Web server, communication server or load balancer comprises means for generating the server certificate request containing the self-address information of the server or the load balancer, means for transmitting the generated server certificate request to the registration server via the network, and means for installing the test certificate generated by the test certificate issuing server and transferred from the registration server for authentication, and said registration server comprises means for receiving the server certificate request transmitted from said Web server, communication server or load balancer, means for transmitting the test certificate issuance request to the test certificate issuing server followed by receiving the certificate request, means for receiving the test certificate generated by the test certificate issuing server and for transferring the received test certificate to the corresponding Web server, communication server or load balancer, means for accessing with SSL protocol to the Web server, communication server or load balancer identified by the address information contained in the server certificate request and for verifying the test certificate installed in said server or load balancer, and means for transmitting the certificate signing request file to the certificate issuing server via a network, and said test certificate issuing server comprises means for generating the test certificate having public key certificate format followed by receiving the test certificate request from the registration server, and means for transmitting the generated test certificate to the registration server, and wherein, said registration server decides that said server certificate request is valid when the session of the SSL protocol has been established and when the certificate information included in the transmitted test certificate is identical to the certificate information included in the installed test certificate, when the registration server accessed to the Web server, communication server or load balancer identified by the address contained in the server certificate request.
