Using Elliptic Curve Cryptography for Authentication and Key Exchange in Constrained Internet of Things Networks

It is anticipated that billions of objects will be interconnected with the rise of the Internet of Things, leading to the evolution of the Internet for the upcoming generation. Various applications have been created in different sectors such as health, logistics, industry, and military in recent years. The techniques created for IoT are still in a nascent stage and encounter numerous hurdles. The primary concern is the security issue. These devices are a significant target due to the numerous conveniences offered by the Internet of Things. These gadgets will maintain continuous communication with one other (M2M) and with people (M2H). It is crucial to ensure the safe transmission of key information about people and the environment throughout this communication. Today's security approaches cannot be integrated into Internet of Things networks because of constraints such as limited RAM, ROM ratio, low bandwidth, poor computing power, and low energy supply. The DTLS protocol, created by IETF, utilizes symmetric encryption and may not be suitable for Class-0 and Class-1 devices that require asymmetric encryption. This study examines the security measures in place and the data is securely exposed to the internet using Elliptic Curve Cryptography, then compared with other studies.
