Abstract

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.
