Internet of Things (IoT) devices have grown in popularity over the past few years. These inter-connected devices collect and share data for automating industrial or household tasks. Despite its unprecedented growth, this paradigm currently faces many challenges that could hinder the deployment of such a system. These challenges include power, processing capabilities, and security, etc. Our project aims to explore these areas by studying an IoT network that secures data using common cryptographic algorithms, such as AES, ChaCha20, RSA, and Twofish. We measure computational time and power usage while running these cryptographic algorithms on IoT devices. Our findings show that while Twofish is the most power-efficient, Chacha20 is overall the most suitable one for IoT devices.
