Searching for impossible subspace trails and improved impossible differential characteristics for SIMON-like block ciphers
Abstract In this paper, we greatly increase the number of impossible differentials for SIMON and SIMECK by eliminating the 1-bit constraint in input/output difference, which is the precondition to ameliorate the complexity of attacks. We propose an algorithm which can greatly reduce the searching co...
