INDIVIDUAL DEVICE, TERMINAL, SERVER, AND METHOD FOR ESTABLISHING RELIABLE CONNECTION BETWEEN USER AND TERMINAL

摘要

PROBLEM TO BE SOLVED: To authenticate a public terminal before a user processes information requiring security by using the public terminal. SOLUTION: When a device 2 for an individual is connected to a terminal 6, a 1st authentication step is started; and the terminal authenticates its server 5 and when the authentication is successful, a 1st secure authenticated connection is established between the server and terminal. Then a 2nd authentication step is started; and the server authenticates itself to the device through the 1st authenticated connection which is already established and when the authentication is successful, a 2nd secure authenticated connection is established between the server and device. Then the device for the individual receives a terminal authentication message confirming the establishment of the authentication of the terminal from the server through the 2nd authenticated connection in a 1st messaging step. Then an authentication output message is transmitted to the user 1 in a 2nd messaging step from the device through the output of the device or the output 3 of the terminal.
