PROBLEM TO BE SOLVED: To provide a network authentication method for guaranteeing secure authentication of a network server and an application related to network transactions.SOLUTION: A user terminal 12 is connected to a network server through execution of an application, and transmits a server verification request to a card device 13 connected to the user terminal 12. The card device 13 generates a server dynamic link program on the basis of a server verification code, further encrypts the server dynamic link program, and transmits the encrypted server dynamic link program to the network server through the user terminal 12. The user terminal 12 receives server code data generated by the network server from the network server on the basis of the server dynamic link program to transmit the server code data to the card device 13. The card device 13 verifies the network server on the basis of the server code data and the server verification code.SELECTED DRAWING: Figure 1 |
