Problems solved by technology

However, the digital certificate will not be renewed within the validity period, and the above method will still repeat the verification of the validity of the digital certificate during the validity period of the digital certificate, resulting in a waste of resources
At the same time, the above method is executed every time, which also increases the time for digital signature verification of the latest digital certificate obtained by the above method

Abstract

The application provides a digital certificate updating method, a digital signature verification method and a digital authentication device, and belongs to the technical field of computer cryptography. The method comprises the steps that a management unit verifies effectiveness of a stored first digital certificate in a preset period; if the first digital certificate is failed, the management unit acquires an effective first digital certificate; and the management unit updates the first digital certificate with the effective first digital certificate. According to the application, the management unit carries out verification on the stored digital certificate in the preset period and when the digital certificate is failed, the effective digital certificate is acquired and the digital certificate is updated into the effective digital certificate, so that the digital certificate is verified for once at an interval of the preset period, rather than is verified for once when a digital signature to be verified is acquired, and thus, resource waste caused by a case that a verification unit carries out verification when acquiring the digital signature to be verified is avoided, and time for the verification unit to subsequently carry out digital signature verification by utilizing the newest digital certificate obtained by the digital certificate updating method is also reduced.

Description

technical field [0001] The application relates to the technical field of computer encryption, in particular to a digital certificate update method, a digital signature verification method and a digital authentication device. Background technique [0002] With the emergence of problems such as network information tampering, the validity of network information has become the focus of attention. Due to its non-repudiation, digital signatures are widely used in the verification of network information and validity. Since digital signatures need to be traded according to the corresponding digital certificates, it is necessary to ensure the digital signature verification method through the digital certificate update method. The certificate is the latest digital certificate. [0003] At present, the digital certificate update method is: after obtaining the digital signature to be verified, determine the corresponding digital certificate according to the digital signature, and verif...
