摘要：

In this paper, we present several new related-key impossible differential attacks on 7- and 8-round AES-192, following the work of Eli Biham et al. [6] and Jakimoski et al. [10]. We choose another relation of the related keys, start attacks from the very beginning(instead of the third round in [6]) so that the data and time complexities are improved largely, and only two related keys are needed instead of 32 in the attacks of [6]. Furthermore, we point out and correct an error in [6] when they attacked 8-round AES-192, then present our revised attacks. Finally, we give a new related-key differential attack on 7-round AES-192, which mainly uses a property of MixColumns operation of AES.
