Embodiment Construction

[0055] A method, device and system for updating a digital certificate provided by the present invention will be described in detail below with specific embodiments in conjunction with the accompanying drawings.

[0056] Such as figure 1 As shown, a method for updating a digital certificate provided by an embodiment of the present invention specifically includes the following steps:

[0057] Step 101, the digital certificate authentication / registration server periodically checks the valid periods of all digital certificates stored locally, and generates digital certificate update notification signaling or short messages for digital certificates that need to be updated.

[0058] The digital certificate authentication / registration server checks the validity period of all digital certificates stored locally, compares them with the current time, and determines the digital certificates that need to be updated, including those that have passed the validity period and are about to exp...

Abstract

The invention discloses a method, a device and a system for updating a digital certificate. The method comprises the following steps that: a digital certificate certification / registration (CA / RA) server transmits a digital certificate update notification; the digital certificate certification / registration server receives a digital certificate update request transmitted by a mobile terminal according to the digital certificate update notice; and the digital certificate certification / registration server signs and issues a new digital certificate to the mobile terminal according to the request. The method, the device and the system for updating the digital certificate solve the problems in the prior art that because a mobile terminal user adopts a manual operation mode to update the digital certificate, the operations are complex, the user experience is poor and the update rate of the digital certificate is difficult to guarantee.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method, device and system for updating a digital certificate. Background technique [0002] In practical network applications, for security policy considerations, digital certificates in mobile terminals (hereinafter referred to as certificates) are usually set to a fixed validity period, such as 1 year, 2 years or 3 years. When the certificate in the mobile terminal is about to expire, the certificate needs to be renewed, that is, a new certificate is used to replace the certificate that is about to expire. [0003] Traditional digital certificate renewal methods can be roughly divided into two categories: tool scanning method and manual method. [0004] The so-called tool scanning method is to use tools to scan certificates (usually server certificates) in a certain network segment to check whether the certificate is about to expire. When the certificate is about to expi...
