Performance Evaluation of Firmware Cryptographic Modules on Various MCU Environments

With the development of IoT(Internet of Things), the combination of ICT(Information and Communications Technologies) is active in devices and systems on off-line and the Hyper Connectivity Age is becoming. This provides convenience and usefulness to users, at the same time provides threats of IT security issue to users. It is possible to utilize the cryptographic module in order to solve the security problems. However applying a cryptographic module in legacy devices gives considerably greater effect on the limited resource of devices and system itself. So it is necessary to select an appropriate level of device environment in order to solve this problem. Therefore, in this paper, after shipping the firmware cryptographic module in a similar environment to MCU chips well known relatively large, it is trying to measure the processing speed of cryptographic functions and to compare and to analyze. It is expected that there will be able to provide an indication of choice of devices for applying the cryptographic functions.
