An AES cryptosystem for small scale network
Ukrit Arom-oon · 2017
The Advanced Encryption standard (AES) cryptosystem for the small scale network presents the implementation of the AES algorithm, FIPS 197, on the microcontroller operated on the real-time operating system (RTOS) for securing data in a small scale network for example as an UAVs wireless communication. The Electronic Code Book (ECB) mode of the AES algorithm is mainly used as the cryptographic core. The RTOS has a scheduler with Pre-emptive scheduling algorithm in which each role is to give access the processor for tasks with higher priority. The target hardware is implemented on the arm cortex-M4. The performances of the implemented system are evaluated based on the communication of UAVs including the control commands and telemetry commands.
