Abstract:
|
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. |
