A performance of the IoT(Internet of Things) device is limited in the CPU, memory and so on. The limited IoT device is required to use these cipher algorithms such as AES(Advanced Encryption Standard), LEA(Lightweight Encryption Algorithm). However, these cipher algorithms have a disadvantage that vulnerable to side-channel attack. Therefore, this paper describes the cipher algorithms and the analysis of the power in side-channel attack. Also this paper suggests for the corresponding robust method of the side-channel attack.
