| Abstract: | High speed, high stability, and low latency of 5G makes Internet of Things (IoT) devices much easier to connect the internet. As more devices connect, security become much important. Most IoT devices use lightweight microcontrollers and often choose AES as encryption method. So, this study presents an optimized AES algorithm for Atmel AVR microcontrollers, by optimizing the standard AES algorithm, to reduce the processing time of each encryption and reduce power consumption at the same time, finally we make it to reduce 171 instruction cycles. To validate our research findings, we implement a smart home system that includes temperature and humidity monitoring, ambient light adjustment, and manual/automatic control mode switching. Performance comparisons between the modified AES (EfficientPtr AES-128) and the standard AES revealed that our approach effectively saves 28.8% of power consumption. We successfully demonstrate a secure and energy-efficient IoT encryption transmission solution by combining encryption techniques with energy-saving measures in smart environments.
