New Impossible Differential Attacks on AES

Zheng Yuan

Abstract

Some new near $5$ rounds impossible differential properties of AES are first presented in this paper, in which active bytes of $1^{s t}$ round or $5^{t h}$ round are in different columns and in favor of extension. Additionally, we first propose the complexities expressions of an universal impossible differential attack, which can help us to rapidly search appropriate impossible differential paths. More importantly, our near rounds impossible differential properties and complexities expressions lead to a series of new impossible differential attacks on 7 rounds AES-128, 7-9 rounds AES-192, and 8-12 rounds AES-256.
