New Impossible Differential Attacks on AES

Jiqiang Lu, Orr Dunkelman, Nathan Keller, and Jongsung Kim

Abstract

In this paper we apply impossible differential attacks to reduced round AES. Using various techniques, including the early abort approach and key schedule considerations, we significantly improve previously known attacks due to Bahrak-Aref and Phan. The improvement of these attacks leads to the best known impossible differential attacks on 7-round AES-128 and AES-192, as well as to the best known impossible differential attacks on 8-round AES-256.
