METHOD FOR ACCESSING TEMPER-PROOF DEVICE AND APPARATUS ENABLING OF THE METHOD

摘要

The present invention relates to a tamper-proof device access method and a terminal device employing the method. According to an embodiment of the present invention, the method includes the steps of: generating a first verification hash value by using a file relevant to the execution of an application when the application is executed; determining whether the first verification hash value matches an integrity value of the application stored in the tamper-proof device; connecting a session of the tamper-proof device and the application when the integrity value and the first verification hash value match; registering a random value generated at each time the application is executed in the tamper-proof device as a handle value of the application; and conducting an encryption or decryption operation by using a key value corresponding to the handle value stored in the tamper-proof device when there is a command coupled with the handle value from the application. The present invention enables the device to conduct the information encryption or decryption operation by using the key value of the tamper-proof device without requiring a password from a user.
