Ultra-Compact Cryptographic Engineering for the Internet of Things: Enhancing Security in Highly Constrained Environments
Abstract
This paper will design a cryptography framework intended to work within extremely lightweight and resource-constrained IoT implementation environments. Its goal is to design a secure and computationally efficient system that will be able to protect the large-scale IoT systems that support the critical infrastructure like healthcare systems, industrial sensors, and smart cities applications. The suggested architecture is a combination of algorithmic design, simulation, and hardware evaluation with the platform that has FPGA and ARM Cortex-M microcontrollers to evaluate the performance of the proposed architecture in real-world conditions. The model has been largely tested, showing substantial energy use (up to 40% of original power usage), increased throughput (up to 30% more), and lower latency (reduced by 20-50%) than more traditional cryptographic standards like AES and PRESENT. These findings establish lightweight encryption as viable with respect to protecting the IoT ecosystems without compromising the cryptographic strength. The area of this study puts its contribution in the context of the current digital transformation of Iraq, drawing on the framework of information-system compatibility of organizational readiness model. It is through such regional inferences that the paper suggests a framework of cryptography, which is engineering-oriented, enabling safe, energy-conscious, and scalable information exchange among national e-management systems. The results support the notion that ultra-lightweight cryptographic engineering can be used as a foundation to developing economies in order to support the development of secure, sustainable, and interoperable digital infrastructures.
