As more information as embedded system handling, it can causes secure and privacy problem. To solve these problem, there are many secure methods and devices like encryption module, but it has critical vulnerability to side-channel attack. Side channel attack can extort encryption algorithm’s key information by analysis algorithm’s power consumption, consumption time, and electromagnetic signal. So we implement sheltered circuit bases AES module and DPA attack SHA2 module. Our proposed sheltered circuit has advantage that stabilize current consumption on every encryption module. In implementation, we use MPW_MS018_1602 version provided by IDEC. Our system’s power is 1.8v, maximum frequency is 10Mhz, and type of chip is mixed one. |
