Abstract
In this paper we present two new attacks on round reduced versions of the AES. We present the first application of the related-key boomerang attack on 7 and 9 rounds of AES-192. The 7-round attack requires only 218 chosen plaintexts and ciphertexts and needs 267.5 encryptions. We extend our attack to nine rounds of AES-192. This leaves to a data complexity of 267 chosen plaintexts and ciphertexts using about 2143.33 encryptions to break 9 rounds of AES-192.
