New Related-Key Boomerang Attacks on AES
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 2^{18} chosen plaintexts and ciphertexts and needs 2^{67.5} encryptions. We extend our attack to nine rounds of AES-192. This leaves to a data complexity of 2^{67} chosen plaintexts and ciphertexts using about 2^{143.33} encryptions to break 9 rounds of AES-192.
