A lightweight cryptography algorithm for secure smart cities and IOT

Lightweight cryptography has a major role in cybersecurity for smart cities and the Internet of Things. It can be further secure by the development of lightweight encryption algorithms that work in restricted devices and with limited specifications such as wireless network sensors. The restricted devices have a small memory, a simple processor, and limited power. To secure them, need lightweight cryptography algorithms and take into account the limited specifications at the same time. In addition, decreasing memory and power consumption in lightweight encryption algorithms, increasing security is also essential. When the lightweight cryptography algorithm is more secure and less consumes memory and energy, it is better and more efficient. In this article, we have developed a lightweight cryptographic algorithm, and through studies, analysis, and comparison with other lightweight cryptography algorithms show that the proposed algorithm is efficient.
