METHOD AND SYSTEM FOR OPERATING A SECRET KEY OF A SECURITY APPLICATION MODULE WHICH GENERATES THE SECRET KEY BY USING CARD INFORMATION FOR GENERATING A SECRET KEY AND A MASTER KEY STORED IN A STORAGE MEDIUM AND A RECORDING MEDIUM FOR THE SAME

摘要

PURPOSE: A method and a system for operating a secret key of a security application module and a recording medium for the same are provided to completely block a hacking or stealing of a master key in the security application module. CONSTITUTION: A storage medium(105) stores a master key which corresponds to a security application module equipped in a wireless terminal. A communication unit(220) receives card information for generating a secret key among card information of a wireless terminal user through the wireless terminal user or a card issuing company. A generation unit(240) generates the secret key by substituting the master key which is previously stored in the card information and the storage medium as a variable. A processing unit(250) processes the secret key in order to store the secret key in the wireless terminal by transmitting the secret key to the wireless terminal.
