Timestamp Based OTP and Enhanced RSA Key Exchange Scheme with SIT Encryption to Secure IoT Devices

Abstract

The Internet of Things (IoT) has become an emerging technology and is expected to connect billions of more devices to the internet in the near future. With time, more and more devices like wearables, intelligent home systems, and industrial automation devices are getting connected to the internet. IoT devices primarily transfer data using wireless communication networks, introducing more vulnerabilities like man-in-the-middle-attacks and eavesdropping. These security concerns are customary for any device communicating over the internet because of its intrinsic open nature. These problems are usually subdued by conventional cryptographic algorithms used in typical systems that are power-hungry and computationally intensive, making them infeasible to be used in IoT devices since they run on low-powered chips, limiting performance, memory, and bandwidth. Hence, there is a requirement to adopt lightweight cryptographic algorithms that can abate the security issues while using low computational resources, which is the constraint in the given scenario. Hence, we propose an end-to-end secured IoT system that ensures the system’s integrity is never compromised using lightweight cryptographic algorithms. We propose a three-module system, where the first module handles user authentication using a time-based one-time password, the second secures communication using lightweight enhanced RSA, and the third performs data encryption using Feistel-based enhanced SIT. This kind of system is designed to deal with security challenges in IoT devices, ensuring adequate data security while reducing the computational footprint using lightweight cryptography.

“…In the field of industrial IoT intrusion security detection, Industrial Control System (ICS) is a comprehensive concept of industrial production control systems, mainly including SCADA systems, DCS systems, and other common small control systems. ICS has become the core of critical infrastructure, and its security is related to national security and social stability, making it an important component of national security strategies [8,9]. Industrial Control Network (ICN), as the core component of ICS, usually uses controllers, sensors, and measurement and control instruments with network communication capabilities as network nodes, and uses industrial Ethernet or fieldbus as communication media to complete the measurement and control functions of industrial data through digital, open, and multi node communication methods [10].…”
