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.

Abstract: The present invention provides a method for protecting the first message of a security protocol and the method includes the following steps: 1) initialization step; 2) the initiating side sends the first message; 3) the responding side receives the first message. The method for protecting the first message of the security protocol provided by the present invention can implement that: 1) Pre-Shared Master Key (PSMK), which is shared by the initiating side and responding side, and the security parameter in the first message are bound by using computation function of Message Integrality Code (MIC) or Message Authentication Code (MAC), and thus the fabrication attack of the first message in the security protocol is avoided effectively; 2) during computing the MIC or MAC of the first message, only PSMK and the security parameter of the first message are selected to be computed, and thus the computation load of the initiating side and the responding side is effectively reduced and the computation resource is saved.
