Signature method and system for digital certificate

Abstract

The invention discloses a signature method and system for a digital certificate. The method comprises the following steps of generating a two-dimensional code for information needed to be signed in a request page when a server end receives a browser access request, and sending the request page containing the generated two-dimensional code to a browser end; scanning and identifying the two-dimensional code by utilizing a mobile terminal to obtain the information contained in the two-dimensional code, thereby obtaining a to-be-signed file; and performing signature on the to-be-signed file by utilizing the mobile terminal, and uploading a signed file to the server end. According to the signature method and system, digital certificate signature of a compute end can be realized through a mobile phone end, so that e-commerce trading of a user is ensured to be securely carried out.

Description

technical field [0001] The invention relates to the field of digital certificate technology, in particular to a digital certificate signing method and system based on two-dimensional code scanning.

[0005] At present, for computer-side users, there is a computer-based CA to complete the electronic signature of the computer-side application, and for mobile phone-side users, there is a mobile-based CA to complete the electronic signature of the computer-side application. Applied CA electronic signature

[0006] In addition, at present, the use of digital certificates on the computer side requires the installation of the CA browser control, and various problems often occur during the installation process, and most digital certificate manufacturers on the market only develop the Microsoft IE browser Supported ActiveX controls, that is, the normal use of most CAs needs to rely on the IE browser. For other browsers, especially newly launched browsers, such as Google Chrom, Mozilla Firefox and Microsoft's latest browser EDGE, they do not support ActiveX Controls, when using these browsers for e-commerce transactions, it is often impossible to achieve the correct signing of digital certificates, which often leads to failure of signing
