Lightweight Elliptical Curve Cryptography (ECC) for data integrity and user authentication in smart transportation IoT system

Abstract

Data integrity and data security are major issues while transferring data in any Internet of Things (IoT) application. The sensor node as an edge node or end node collects information from the physical environment which is to be preprocessed and sent to the nearby server or cloud server for storage or for further processing. Because of the constrained resources at the edge node, it is essential to perform edge analytics with methods which utilize less power or can be performed with less computational complexity with limited memory. In this scenario, the data security related methodology should use lightweight encryption method for providing data security to avoid the attacks on data integrity while transmitting. In our Smart Goods Transport IoT system, we are using lightweight encryption method Elliptical Curve Cryptography (ECC) using ElGamal encryption scheme to provide strong authentication and data security while in transit.
