Abstract
In this paper we examine the strength of AES against the related-key impossible differential attack, following the work of Jakimoski and Desmedt [12]. We use several additional observations to substantially improve the data and time complexities of their attacks. Amongst our results, we present a related-key attack on 7-round AES-192 with data complexity of 256 chosen plaintexts (instead of 2111). Our attack on 8-round AES-192 has data complexity of 268.5 chosen plaintexts (instead of 288). The time complexities of our attacks is also substantially lower than the time complexities of previous attacks.
