SECURITY INFORMATION INTERACTION DEVICE AND METHOD, AND IC CARD FOR SECURITY INFORMATION INTERACTION

摘要

Provided are a security information interaction device and method, and IC card for security information interaction, the security information interaction method comprising the following steps: (A1) the security information interaction device transmits to the IC card the first part of the security information inputted by a user; (A2) the IC card checks the first part of the security information based on the second part of the security information and a check code, constructs a response based on the check result, and transmits the response back to the security information interaction device; and (A3) if the response indicates "Check Successful", then the security information interaction device constructs a data interaction request, and transmits the data interaction request to a data processing server to complete subsequent data processing. The security information interaction device and method, and the IC card for security information interaction disclosed by the present invention have high security.
