Abstract:

The Internet of Things (IoT) has experienced rapid expansion, changing how researchers use and view technology. The security and privacy of data transmitted within IoT networks have become crucial concerns as IoT devices become increasingly widespread. This study describes a method for improving the security characteristics of IoT communication protocols by leveraging a lightweight cryptographic mechanism in a 5G-enabled IoT device with limited power and memory, commonly referred to as a resource-constrained device. Traditional cryptographic algorithms designed for high-performance systems can be impractical for these devices. A lightweight cryptographic technique offers robust security while optimising resource usage. In this work, researchers investigate the uses of hash functions and light-weight block cyphers in the context of IoT communication protocols. In this work, researchers propose integrating lightweight cryptography into IoT communication protocols to address common security challenges, including data confidentiality, integrity, and authentication. Researchers also examine the impact of lightweight cryptography on key management processes, such as key generation and distribution, in resource-constrained IoT environments, and present experimental results and performance metrics demonstrating its effectiveness in enhancing the security of IoT communication protocols without imposing undue burdens on IoT devices.

Keywords: IoT Security; Communication Protocol; Lightweight Cryptography; Data Confidentiality; Data Integrity; Internet of Things (IoT); Resource-constrained Devices.
