WIRELESS DATA ENCRYPTION AND DECRYPTION USING IOT

Secure exchange of data is critical in IoT-based applications, especially for resource-limited devices such as the Arduino Uno. The project creates a secure data transmission system through serial communication via TX and RX lines, incorporating an XOR-based encryption scheme lightweight enough for efficient data protection. AES decryption is employed to enhance security during data reception to preserve both confidentiality and integrity. In addition, the ESP8266 Wi-Fi module supports encrypted data delivery to cloud services, providing realtime monitoring and remote visualization. This approach allows for secure communication even over public networks, providing a cost-effective and scalable solution for IoT applications like industrial automation, sensor networks, and smart environments at low computational overhead
