This paper reports on higher-order square analysis of the AES cipher. We present experimental results of attack simulations on mini-AES versions with word sizes of 3, 4, 5, 6 and 7 bits and describe the propagation of higher-order Lambda-sets inside some of these distinguishers. A possible explanation of the length of the square distinguishers uses the concept of higher-order derivatives of discrete mappings.
