Abstract
In this paper, we study the security of AES-192 against related-key differential-linear cryptanalysis, which is the first attempt using this technique. Among our results, we present two variant attacks on 7-round AES-192 and one attack on 8 rounds using a 5-round related-key differential-linear distinguisher. One key point of the construction of the distinguisher is the special property of MC operation of AES. Compared with the best known results of related-key impossible differential attacks and related-key rectangle attacks on AES-192, the results presented in this paper are not better than them, but the work is a new attempt, and we hope further work may be done to derive better results in the future.
