Data Security for Internet of Things (IoT) Using Lightweight Cryptography (LWC) Method

The notion of Internet of Things (IoT) is significant in the continuing development of the Internet since it describes the creation of a network of tiny objects that may link countless numbers of devices from different platforms. In order to enable an efficient end-to-end communication – Ensuring total security usually requires the implementation of an algorithm with a symmetric key on the final nodes. For applications with few assets, like those run on batteries, cryptographic functionality with low energy consumption is essential. Using the lightweight symmetric key approach can result in end devices using less energy. In order to defend IoT systems against memory heap assaults, this effort aims to build a security paradigm. For this purpose, a Light Weight Cryptography (LWC) model based on Elliptic Curve Cryptography (ECC) is deployed in this work. Moreover, the one-way hash algorithm is used to protect the memory heap with high efficiency and attack detection rate. Based on the computational time metrics, the suggested LWC-ECC model’s performance and outcomes are verified and compared.
