Equivalence of XOR and XNOR in differential cryptanalysis: application to SCAN-C

Abstract SCAN-C is a lightweight block cipher featuring a hybrid Feistel-SPN structure designed for Controller Area Network (CAN) security. This work presents the first full-round differential cryptanalysis of SCAN-C, demonstrating that its unique XNOR-based key mixing provides n...
