Krishnendu T. S, Piyoosh Purushothaman Nair · 2024
The advent of the Internet of Things (IoT) is one of the most dynamic and exciting developments in information and communications technology which helps to ease the daily life of end users. However, the transmission of large amounts of private information transmitted through a network brings serious security and privacy concerns. The limited availability of resources like computing resources, memory, and power resources remain major challenges for implementing security in IoT. In this paper, we propose a highly secure lightweight authentication and data transmission scheme for smart IoT devices that acts as a countermeasure against various security vulnerabilities of the IoT environment and also meets the resource requirements of the IoT. The scheme uses Silicon Physical Unclonable Function (PUF) technology to uniquely identify each edge node in the IoT. We rely on the Long Range Wide Area Network (LoRaWAN) for secure data transmission. All the methods in the proposed scheme are based on symmetric and lightweight cryptographic techniques which helps to reduce the computing power and energy requirement of the scheme. The proposed scheme is shown to be secure against various well-known attacks. Moreover, the proposed scheme achieves significantly lower energy consumption (ranging from 50% to 60%), reduced storage costs (ranging from 42% to 61%), decreased communication costs (ranging from 36% to 76%), and lowered computational costs (ranging from 14% to 66%) when compared to existing schemes.
