ePrint Report: Differential Cryptanalysis of a Lightweight Block Cipher LELBC

Manjeet Kaur, Tarun Yadav, Manoj Kumar, Dhananjoy Dey

In this study, we investigate the newly developed low energy lightweight block cipher (LELBC), specifically designed for resource-constrained Internet of Things (IoT) devices in smart agriculture. The designers conducted a preliminary differential cryptanalysis of LELBC through mixed-integer linear programming (MILP). This paper further delves into LELBC’s differential characteristics in both single and related-key frameworks using MILP, identifying a nine-round differential characteristic with …
