A COMPREHENSIVE ANALYSIS OF LIGHTWEIGHT HASH FUNCTIONS IN THE IOT ENVIRONMENT

Security in IoT

The exponential growth of the Internet of Things (IoT) in recent years is attributed to its profound impact on various aspects of daily life, particularly in critical applications such as healthcare, smart homes, smart cities, and broader smart infrastructure. This surge has drawn the attention of industries and researchers, prompting them to delve into the development of IoT technology. However, the vulnerability of IoT devices is evident due to their limited network capacities, minimal computing power, short battery life, and constrained data storage capabilities. The primary challenge hindering the widespread adoption of IoT systems is the imperative need for lightweight and energy-efficient security solutions. These solutions aim to safeguard smart devices and the sensitive data they store. Therefore, this study explores the integration of lightweight hash algorithms to verify data integrity and enhance the security of IoT systems. Given that hashing plays a pivotal role in establishing a resilient IoT framework, we opt to implement various hash techniques on a Raspberry Pi/Arduino/ESP32 device. In conclusion, this research offers a quantitative analysis to assess the performance of renowned hash functions applicable to lightweight IoT framework and resource constrained IoT devices.
