Method and system for electronic signature and mobile communication terminal used for electronic signature

Abstract

The invention relates to a method and system for electronic signature and a mobile communication terminal used for electronic signature. The method includes the following steps: an electronic signature platform generates a two-dimensional code of a document to be signed based on a first electronic signature request sent by a user, and sends the two-dimensional code to a mobile communication terminal of the user; the mobile communication terminal scans the two-dimensional code and displays two-dimensional code information to the user, and requests the electronic signature platform for abstract values of the document to be signed based on a second electronic signature request of the user; the electronic signature platform generates abstract values and returns to the mobile communication terminal; the mobile communication terminal uses a user certificate stored therein to perform digital signature on the abstract values, and sends the digitally signed abstract values to the electronic signature platform to request for a document with a generated signature; and the electronic signature platform embedded the digitally signed abstract values into the document to be signed, and returns the document with the generated signature to the user. The electronic signature method provided by the invention is relatively safe, simple and rapid, and is low in cost.

Description

technical field [0001] The present invention relates to electronic signature technology, more specifically, to an electronic signature method and system and a mobile communication terminal for electronic signature. Background technique [0002] With the in-depth application of information technology and computer networks in various fields of society, the application of electronic collaborative office is becoming more and more extensive, and its advantages of high efficiency and resource saving are also becoming increasingly prominent. In electronic collaborative office, how to ensure the integrity and confidentiality of electronic documents, the verifiability of the identity of the document sender and the non-repudiation of the signer have become urgent problems to be solved. Electronic signature technology is formed under this demand and becomes an indispensable technical means. [0003] In the current electronic signature process, the signature is realized in the followin...

Problems solved by technology

[0007] Browser control method: PIN code setting is simple and convenient, and the cost is low, but it cannot prevent unsafe factors such as brute force cracking and hacking, and problems such as control compatibility also lead to poor user experience

[0008] Encryption machine method: The encryption machine has a high level of security and is the first choice for large enterprises and institutions. However, because the encryption machine is a unique encryption hardware, it needs to invest in hardware costs. Compared with other electronic signature methods, the cost is relatively high
