Embodiment 1

[0037] The embodiment of the present invention provides a system for downloading digital certificates, such as figure 1 , 2 As shown, the system includes: a client terminal 101, which is used to download a control unit, and the control unit includes at least a certificate download unit 201; wherein, the client terminal 101 uses the certificate download unit 201 to generate a certificate request, and sends the certificate request;

[0038] The CA server 102 receives the certificate request sent by the client 101, generates a corresponding digital certificate, and returns the digital certificate to the client 101;

[0039] And, after receiving the digital certificate, the user terminal 101 uses the certificate downloading unit 201 to parse out the user certificate and save it in the digital signature device;

[0040] A digital signature device (not shown in the figure) is connected to the client and stores the parsed user certificate.

[0041] It can be seen from the above tha...

Embodiment 2

[0117] The invention also provides a method for downloading digital certificates. The method includes the steps of:

[0118] Download the control unit to the client terminal 101; the client terminal 101 uses the control unit to download the digital certificate to the digital signature device.

[0119] Through the above embodiment, when downloading the digital certificate, the control unit is directly used, thereby reducing the intermediate links of data transmission, avoiding the risk of sensitive data being intercepted by hackers, and eliminating the trouble caused by the user's additional installation of middleware CSP programs , avoiding the risks brought about by the compatibility of operating systems of different versions of Windows and upgrading new functions, and greatly improving the ease of use.

[0120] In one embodiment of the present invention, the user terminal 101 uses the certificate download unit 201 of the control unit to download the digital certificate of t...

Abstract

The invention provides a method for downloading digital certificates, which comprises the following steps: downloading a control unit to a user end, utilizing a certificate downloading unit of the control unit to download digital certificates to a digital signature device by a user end. With the invention, when realizing the downloading of the certificates, intermediate links of data transmissionare reduced through utilizing the control unit, dangers that sensitive data is captured by hackers are effectively prevented, simultaneously, troubles due to additionally installing a middleware CSP process by the user are eliminated, dangers due to the compatibility and updating new functions of the variant edition of Windows are prevented, and the usability is greatly improved.

Description

technical field [0001] The present invention relates to a digital signature device technology, in particular to a digital certificate downloading technology based on a digital signature device supporting a public key system (PKI: Public Key Infrastructure), and in particular to a method and system for downloading a digital certificate. Background technique [0002] With the development of the Internet and the wide application of Internet banking, e-commerce, and e-government, PKI-based digital certificate technology, smart card technology and USBKey are widely used in various industries and regions. More and more Internet users accept and use digital signature devices such as smart cards and related supporting software technologies as methods for identity authentication and digital signatures. [0003] PKI digital certificate technology is a security technology, which is composed of public key cryptography, digital certificates, certificate issuing authority (CA: Certificate...
