  • Patent number: 8250361
    Abstract: A server certificate issuing system in which existence of a Web server for which a certificate is to be issued can be confirmed and security is further improved is realized, wherein the user authentication is carried out using a test certificate having the SSL certificate format. Servers transmit server certificate request to the registration server which transmits the test certificate request to the test certificate issuing authority. The test certificate issuing server transmits the generated test certificate to the registration server which transmits the test certificate to the corresponding server and requests to install the test certificate. Then, the registration server accesses with SSL protocol to the server and verifies whether or not the session of the SSL protocol has been established. The registration server transmits the CSR to the certificate issuing server only when the SSL protocol has been established.

  • Patent number: 8234490
    Abstract: In a server certificate issuing system according to the invention, the Web server includes a control panel which configures and manages a Web and a mail. The control panel is loaded with an entry screen generator to input application items for an issuance of a server certificate, password generator for generating a password which is used to encrypt, and a verification page generator to indicate intention of requesting the issuance of the certificate. On the verification page, the generated password is indicated as verification information for example. The registration server retrieves the password from the received server certificate request and accesses the Web server to read out the verification information indicated on the verification page, and compares the read verification information with the password.

  • Patent number: 7673331
    Abstract: A server certificate issuing system confirms existence of a Web server for which a certificate is to be issued. The web server includes means for generating an entry screen to input application matters for an issuance of a server certificate, means for generating a key pair a public key and a private key, means for generating a certificate signing request file (CSR) containing the generated public key, and means for generating a verification page indicating intention of requesting the issuance of the certificate. A registration server retrieves the CSR from a received server certificate request and accesses the Web server to read the verification information, and compares the read verification information with the CSR. If the verification information read from the Web server is identical to the CSR, it is determined that the Web server for which the server certificate is to be issued exists.
