ENCRYPTION APPARATUS SECURE TO POWER ANALYSIS ATTACK AND OPERATING METHOD THEREOF

摘要

PURPOSE: An encryption device and operation method thereof are provided to supply similarity between a voltage value or a current value that is outputted from an encryption module. CONSTITUTION: An encryption module(110) performs an encryption algorithm. A control module(200) supplies an electric charge from external power supply. The control module transfers the electric charge to the encryption module. The control module blocks a current path between the encryption module and the external power supply.
