The Partial Sum Attack is one of the most powerful attacks developed in the last 15
years against reduced-round versions of AES. We introduce a slight improvement to
the basic attack which lowers the number of chosen plaintexts needed to successfully
mount it. Our version of the attack on 6-round AES can be carried out completely
in practice, as we demonstrate providing a full implementation. We also detail the
structure of our implementation, showing the performances we achieve.
