Title:
Practical Attacks on Reduced-Round AES
Authors: Navid Ghaedi Bardeh, Sondre Rønjom
Abstract:In this paper we investigate the security of 5-round AES against two different attacks in an adaptive setting. We present a practical key-recovery attack on 5-round AES with a secret s-box that requires 2^{32} adaptively chosen ciphertexts, which is as far as we know a new record. In addition, we present a new and practical key-independent distinguisher for 5-round AES which requires 2^{27.2} adaptively chosen ciphertexts. While the data complexity of this distinguisher is in the same range as the current best 5-round distinguisher, it exploits new structural properties of 5-round AES.
