Embodiment Construction

[0039] The present invention will be further described below in conjunction with specific examples, but the present invention is not limited to these specific implementations. Those skilled in the art will realize that the present invention covers all alternatives, modifications and equivalents as may be included within the scope of the claims.

[0040] This patent utilizes the feature of no drive and no software realized by the system equipment. When it leaves the factory, there is a signature authentication component inside the device. By using the binding between the component and the device and using the shared key method, the system software will send the transaction data. Verify the authenticity of the data to ensure that the data received by the device has not been illegally tampered with in the network link.

[0041] First of all, when the device leaves the factory, the system software has been stored in the safe storage space of the device, and the system software has...

Abstract

The invention discloses a method based on USBKey online banking trade information authentication; when being used for the first time, system software is automatically mounted into an operating systemand a solidifying key is mounted simultaneously; when a user finishes pressing a trade fingerprint to confirm the trade, application software generates a random number and uses the solidifying key toencrypt and transmit to a USBKey; meanwhile, the application software uses the random number to implement inserting and upsetting on the received trade data and uses the solidifying key to encrypt andtransmit to the USBKey; the USBKey uses the shared solidifying key to decrypt to obtain one random number and a string of trade data upset by the random number, uses the shared key to take out the random number inserted into the trade data and compares the random number with the random number obtained by directly deciphering, and the random number is confirmed to be true and valid if the resultsare the same. The invention can guarantee the trade information to be safely transferred in the network links by establishing a data truth authentication system, stop the trade information from beingmaliciously altered and protect the user trade to be safely and validly executed.

Description

technical field [0001] The invention relates to a network data authentication method and system, in particular to a method for authenticity authentication of information data sent by an application system. Background technique [0002] With the rapid development of network technology, online transactions are gradually accepted by the public due to their convenience and low cost of use, and the number of users of online transactions is gradually increasing. However, the security of online transactions has gradually become the focus of attention of users. There are more and more reports of online transaction security incidents caused by "Trojan horse" or "broiler" programs, and a large number of users are increasingly worried about online transactions. [0003] The existing client identity authentication system for online transactions is based on U-shield as the technical core. For example, ICBC’s online banking, in terms of transaction security, ICBC uses U-shield to protect ...
