Analyzing message authentication methods and security standards in communication among IoT devices

The rapid expansion of the Internet of Things (IoT) has led to an increasing number of interconnected devices, raising concerns about the security and privacy of data communication.This study analyzes various message authentication methods and security standards employed in IoT device communication to identify their strengths, weaknesses, and opportunities for improvement.The state-ofthe-art message authentication techniques, such as symmetric and asymmetric cryptography, digital signatures, and lightweight authentication protocols are fully reviewed.Additionally, the most common security standards and protocols, focusing on the context of message authentication are also examined, and provide a detailed overview of their usage, advantages, and disadvantages.The findings emphasize the importance of selecting appropriate authentication methods and security standards considering IoT applications' specific requirements and constraints, including computational capacity, energy consumption, and latency.Furthermore, we propose recommendations for enhancing the security of IoT communication and discuss potential research directions in developing novel authentication techniques and security standards tailored to the unique challenges of the IoT ecosystem.
