Abstract
In a digital certificate automatic application method, device and system, a digital certificate applicant notifies a digital certificate issuer of supported digital certificate generation methods. If a digital certificate issued by the issuer is available, then the issuer is notified of the existing digital certificate information. Otherwise, the issuer is notified of the certificate information required to be contained in a newly applied digital certificate. The issuer selects a digital certificate generation method from the digital certificate generation methods supported by the applicant, and notifies the applicant. If the applicant must apply for a new digital certificate, then the new digital certificate information is generated and the applicant is notified. Otherwise, the applicant is notified of the invalid digital certificate information. The applicant determines the digital certificate to be used according to the notification from the issuer. The present application achieves automatic application, updating and issuing of a digital certificate.
