The Partial Sum Attack is one of the most powerful attacks, independent of the key schedule, developed in the last 15 years against reduced-round versions of AES. In this chapter, 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.

Abstract

The Partial Sum Attack is one of the most powerful attacks, independent of the key schedule, developed in the last 15 years against reduced-round versions of AES. In this chapter, 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.
