Abstract
With the advances of Internet-of-Things (IoT) applications in smart cities and the pervasiveness of network devices with limited resources, lightweight block ciphers have achieved rapid development recently.
Due to their relatively simple key schedule, nonlinear invariant attacks have been successfully applied to several families of lightweight block ciphers.
This attack relies on the existence of a nonlinear invariant
