Information interaction method and system and smart key equipment

Abstract

The invention provides an information interaction method and system and smart key equipment. The information interaction method comprises the steps that a server and the smart key equipment conduct session key negotiation operation, if the session key negotiation operation is successfully conducted, a first session key is generated by the server, a second session key is generated by the smart key equipment, and the first session key and the second session key are a key pair; the server uses the first session key to encrypt transaction data, generates the encrypted transaction data and sends the encrypted transaction data to a terminal; the terminal receives the encrypted transaction data and sends the encrypted transaction data to the smart key equipment; the smart key equipment receives the encrypted transaction data, uses the second session key for decrypting the encrypted transaction data, obtains the transaction data, processes the transaction data, obtains transaction key information and sends the transaction key information to the terminal; the terminal receives and displays the transaction key information, generates confirmation information after obtaining a confirmation instruction and sends the confirmation information to the smart key equipment.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an information interaction method, system and intelligent key device. Background technique [0002] In recent years, with the rapid development of the Internet and financial informatization, online banking has been widely praised by users and the banking industry for its convenience and high efficiency. At the same time, transaction security issues have become increasingly prominent. Therefore, the best way to ensure transaction security In order to use the electronic key device while using online banking, at present, the electronic key device can be a smart key device, such as USB-KEY, audio KEY or Bluetooth KEY, etc., or a smart card, such as an IC card. From a technical point of view, the smart key device is a tool for electronic signature and data authentication. It has a built-in micro security chip and uses a key algorithm to encrypt, decrypt and digitally sign transact...

AI Technical Summary

Problems solved by technology

If the display screen and confirmation key are removed, the volume of the smart key device can be effectively reduced, but the smart key device cannot display the transaction data, and the terminal obtains the transaction data in plain text and displays it. If the terminal is hacked or infected by a virus, the transaction data is tampered with , the user cannot know that the transaction data has been tampered with, nor can he obtain the real transaction data. When the user confirms the operation based on the tampered transaction data displayed on the terminal, the smart key device essentially signs the illegal transaction data. caused the loss of the user's property
