Lightweight cryptography has a major role in cybersecurity for smart cities and the Internet of Things, and it can be further secured 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 and a simple processor and limited power, and to secure them need lightweight cryptography algorithms and take into account the limited specifications at the same time. In addition to the importance of decreasing memory and power consumption in lightweight encryption algorithms are important, increasing security is more important. When the lightweight cryptography algorithm more secure and less consumption of memory and energy that means 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 more efficient.
