Zigbee Based Secure Wireless Communication Using AES

ABSTRACT In the rapidly growing domain of wireless communication, data security has emerged as a critical requirement, especially in resource-constrained embedded systems. This paper proposes a secure wireless communication system based on ZigBee technology and Advanced Encryption Standard (AES), implemented using Arduino microcontrollers. The system comprises a transmitter that accepts data via a keyboard, encrypts it using AES-128, and transmits it wirelessly via ZigBee. The receiver decrypts the data and displays it on an LCD. Leveraging ZigBee’s low-power and low-data-rate characteristics, the design ensures secure, efficient, and scalable communication suitable for applications such as home automation, military systems, and industrial control. The integration of AES encryption ensures end-to-end data confidentiality without significantly impacting transmission speed or energy consumption. Performance evaluation confirms the system’s viability for Internet of Things (IoT) applications demanding both security and efficiency.
