Secure lightweight cryptosystem for IoT and pervasive computing

Abstract

AbstractLarge volumes of sensitive data are being transferred among devices as the Internet of Things (IoT) grows in popularity. As a result, security measures must be implemented to ensure that unauthorized parties do not obtain access to the data. It is well acknowledged that IoT devices have restricted resources, such as limited battery life, memory, and hence reaction time. Classical encryption approaches and methods become inefficient for IoT devices due to memory limits. Large volumes of sensitive data are being transferred between devices as the Internet of Things (IoT) grows in popularity. This involves the implementation of security safeguards to ensure that unauthorized parties do not obtain access to the data. IoT devices are notorious for having limited resources, such as battery life, memory, and hence response time. Classical encryption approaches and methods become inefficient for IoT devices due to memory limits. As a result, a Lightweight cryptosystem that fits the needs of Lightweight devices and ubiquitous computing systems has emerged. The goal of this study is to present a Lightweight cryptosystem (LWC) that may be used as a plugin to secure data transfers in IoT devices and pervasive computing. To that goal, the researchers employ several simple measuring techniques. The suggested system was then implemented on a field-programmable gate array (FPGA) board using the Verilog programming language to demonstrate its appropriateness for actual security applications. FPGA is also utilized in hardware applications to assess the system’s resource usage and performance. Finally, a comparison of the proposed system with previous lightweight cryptography systems is performed to reinforce the major goal of this work, which is to present a new lightweight cryptosystem.
