Problems solved by technology

Then, to use the USB Key, you need to install the corresponding driver, and different terminals and different systems will cause many problems when installing the driver, making it difficult for users to install and use; and because the USB Key does not have a good connection method with the mobile device, the USB Key certificate cannot be issued. Used on various mobile devices; at the same time, signing with a USB Key device cannot prevent man-in-the-middle attacks and Trojan horse attacks from stealing certificates

Embodiment 1

[0097] The present invention provides a digital certificate signature method. The system implementing the method includes an authentication institution, an institution that needs to authenticate the identity of the user, and a client. The method includes the following steps:

[0098] A1. The customer sends a business request to the organization that needs to authenticate the user's identity;

[0099] A2. The organization that needs to authenticate the user's identity sends the data to be signed to the customer;

[0100] A3. The customer uses an independent digital signature device to receive the data to be signed;

[0101] A4. The client uses an independent digital signature device to sign;

[0102] A5. The customer uses an independent digital signature device to send the signed data back to the organization that needs to authenticate the user's identity;

[0103] A6. The organization that needs to authenticate the user's identity receives the signed data;

[0104] A7. The ...

Abstract

The invention relates to a method and system for digital certificate signing. According to the method and system, an independent digital certificate signing device is used for carrying out reception of information needing countersigning, signing and signature information sending. Therefore, problems that the traditional USB key type certificate device can not prevent the Trojan attack and man-in-the-middle attack and can not be used at the mobile device easily can be solved. Meanwhile, a drive problem existing in the traditional USB key type certificate device can be solved, so that the terminal client can use the digital certificate signature securely and rapidly.

Description

technical field [0001] The present invention relates to the method and system field of digital certificate signature. Background technique [0002] Digital authentication certificate is an encryption technology with digital certificate as the core, which can encrypt and decrypt information transmitted on the network, digital signature and signature verification, to ensure the security and integrity of information transmitted on the Internet. With the use of digital certificates, even if the information you send is intercepted by others on the Internet, or even if you lose your personal account, password and other information, your account and fund security can still be guaranteed. Simply put, it is to ensure the safety of your online transactions. [0003] The digital verification devices in the prior art are all usb devices, such as the patented digital certificate authentication method, system, USB Key device and server with application number 201110247312.9, which disclo...
