ABSTRACT:
There is provided a communication systems in which a public key certificate is easily updated. The administration PC transmits SSL communication request to the print server which is searched by the print server search broadcast. If the server certificate (public key certificate) received from the print server at the time of SSL handshake is determined to be likely to expire, the CSR create request and the CSR parameters are transmitted to the print server. The print server creates CSR based on the received CSR parameters, and transmits the CSR to the administration PC. The administration PC transmits the received CSR to the CA. The CA generates the server certificate based on the received, and transmits the CSR to the administration PC20. The administration PC transmits the certificate install request and the server certificate to the print server. The print server updates the server certificate by installing the received server certificate.
