Electronically signing method and system

Abstract

The invention provides an electronically signing method and system, wherein the method includes the steps that a first terminal obtains an encrypted transaction message and first encrypted data, sends the encrypted transaction message and the first encrypted data to a first electronic signature token to conduct signing and obtains first signature information, the first terminal sends a first data package to a second terminal, the second terminal conducts signing verification on the first signature information and sends the first encrypted data to a second electronic signature token after the first signature information passes the verification, the second electronic signature token conducts decryption on the first encrypted data to obtain a first encryption strategy and sends the first encryption strategy to the second terminal, the second terminal conducts decryption on the encrypted transaction message to obtain the transaction message according to the first encryption strategy and sends the transaction message to the second electronic signature token to conduct signing to obtain message signature information, the second terminal sends a second data package to the first terminal, and the first terminal obtains the message signature information. Through the electronically signing method and system, the problem that potential safety hazards are caused and the use is inconvenient due to the uniqueness of the electronic signature token is solved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an electronic signature method and system. Background technique [0002] At present, with the popularity of online banking and mobile banking, electronic signature tokens connected to transaction terminals through USB (Universal Serial Bus) interfaces or audio interfaces are also being used more and more. Electronic signature tokens It can be, for example, USB Key, U-shield, mobile phone shield and other devices that can realize electronic signatures used by major banks. The specific method of using the electronic signature token now is that the user connects the electronic signature token to the transaction terminal, the transaction terminal receives the transaction instruction and transaction information and generates a corresponding transaction message, and sends it to the electronic signature token, and the electronic signature token The card extracts specific tr...
