Abstract
The Internet of Things (IoT) refers to the vast network of interconnected devices that collect, exchange, and analyze data, enabling automation and improved efficiency in various domains. However, the rapid growth of IoT also raises significant security concerns. With the unlimited number of devices connected to the internet, the IoT ecosystem becomes a prime target for cyberattacks, threatening the privacy, integrity, and availability of data, decentralization as well as the safety of individuals and critical infrastructure. The challenges mentioned above are inherent attributes of a novel and emerging technology, blockchain. The need to address challenges in the realm of IoT has led to the combination of it with Blockchain technology, prompting scholars to explore the most effective ways to leverage blockchain's capabilities in this context. The ubiquitous implementation of the IoT requires a uniform and resilient framework that can ensure security, compliance with data retention regulations, and efficacy in terms of commercial viability. The Lightweight Secure Blockchain (LSB) is among the various blockchain variations and arrangements created to address these requirements. This research focuses on improving security and performance by implementing various measures, including encryption of transaction delivery, enhancement of transaction flow, verification of blocks, optimization of hash rate, and improvement of hash quality. For the improved effectiveness of the research conducted in the field of IoT, an empirical evaluation was carried out using data collected from the Vainu Bappu Observatory (Indian Institute of Astro Physics, Kavalur) and the Temperature sensor. The study showcases achievements by implementing and comparing outcomes with the standard LSB. The utilization of the hybrid Edward Curve El Gamal approach in transaction encryption has been found to improve the security of transmitted transactions.
