The system includes a mobile device with built-in and external security chips, as well as a certificate authority server that communicates with the mobile device to verify the confirmation code and issue the public key certificate.

The certificate system outlined in the patent involves a mobile device with security chips generating public and private keys, sending a certificate signing request to a certificate authority server, and receiving a public key certificate. The certificate authority server verifies the confirmation code using an external public key, issues the public key certificate, and sends it to the mobile device. The system ensures security by storing the public key certificate in a password-protected area and includes features such as generating a confirmation code based on the signing request and random number, as well as not issuing the certificate if verification fails. The system aims to enhance security and convenience in certificate requesting and issuing processes.
