Abstract:
Provided is a method of updating an integrity check value (ICV) stored in a hardware security module (HSM). The method includes storing user authentication information of the terminal transferred from the terminal to preregister a user of the terminal, transferring an authentication information request message, requesting the user authentication information, to the terminal in response to an update request message which is transferred from the terminal and includes an update value of the ICV, comparing the user authentication information transferred from the terminal with the stored user authentication information to perform an authentication operation on the user of the terminal according to the authentication information request message; and when the user of the terminal is successfully authenticated, updating the stored ICV by using the update value.
