Secure and Efficient Data Transmission in Internet of Things (IoT) Networks: A Review of Protocols and Techniques

Abstract

This paper provides a comprehensive review of secure and efficient data transmission techniques in Internet of Things (IoT) networks, focusing on protocols, encryption algorithms, and authentication mechanisms. It examines the unique challenges posed by IoT environments, such as resource constraints, heterogeneous devices, and vulnerability to cyber attacks, and evaluates existing solutions to mitigate these risks. The research highlights the importance of end-to-end encryption, secure bootstrapping, and access control mechanisms in safeguarding IoT data integrity and confidentiality. Additionally, it identifies emerging trends and future research directions to address evolving security threats in IoT ecosystems.
