Improved Key Recovery Attacks on Reduced-Round AES in the Single-Key Setting
[chapter]
2013
Lecture Notes in Computer Science
In this paper, we revisit meet-in-the-middle attacks on AES in the single-key model and improve on Dunkelman, Keller and Shamir attacks of Asiacrypt 2010. We present the best attack on 7 rounds of AES-128 where data/time/memory complexities are below 2 100 . Moreover, we are able to extend the number of rounds to reach attacks on 8 rounds for both AES-192 and AES-256. This gives the best attacks on those two versions with a data complexity of 2 107 chosen-plaintexts, a memory complexity of 2 96
