Embodiment 1
[0031] An embodiment of the present invention provides a digital signature system, which includes:
[0032] The user terminal is used to download the control unit, and the user terminal uses the digital signature control unit to complete the data input, and sends the input data;
[0033] A digital signature device, connected to the client, used to receive the data sent by the control unit, digitally sign the data and obtain the signature result;
[0034] In addition, the control unit receives the signature result, organizes the signature result and related information into signature data, and displays the obtained signature data in a designated area of the webpage.
[0035] In the above implementation manner, the data that needs to be signed may be designated data or a form in a webpage. The relevant information refers to the original text of the signature data and the certificate corresponding to the signature key.
[0036] It can be seen from the above that when performi...
Embodiment 2
[0047] The invention also provides a digital signature method. The method includes the steps of:
[0048] Download the control unit to the client; the client uses the control unit to digitally sign the data that needs to be signed by the digital signature device.
[0049] Through the above embodiment, the control unit is directly used for digital signature, thereby reducing the intermediate links of data transmission, avoiding the risk of sensitive data being intercepted by hackers, and removing the trouble caused by the user's additional installation of middleware CSP programs, avoiding The compatibility of different versions of Windows operating systems and the risks brought by upgrading new functions greatly improve the ease of use.
[0050] In an embodiment of the present invention, the user terminal uses the control unit to digitally sign the data that needs to be signed by the digital signature device, and the following methods can be used: use the control unit to compl...

Abstract
The invention provides a digital signature method. The method comprises the steps of: downloading the control unit to the user end; using the control unit to complete data input; the control unit sending the input data to the digital signature device; the digital signature device performs a digital signature and obtains a signature result; the control unit Organize signature results and related information into signature data. Through the present invention, when implementing digital signatures, the use of the control unit reduces the intermediate link of data transmission, effectively avoiding the risk of sensitive data being intercepted by hackers, and at the same time removing the trouble caused by the user's additional installation of middleware CSP programs, avoiding Windows The compatibility of different versions of the operating system and the risk of upgrading new functions greatly improve the ease of use.
Description
technical field [0001] The present invention relates to a digital signature device technology, in particular to a digital signature technology based on a digital signature device supporting the function of a public key system (PKI: Public Key Infrastructure), in particular to a digital signature method and system. 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 Authority), and secur...
