In this paper we present a tweak for the key schedule of AES in a form of a few additional basic operations such as rotations and S-boxes. This leads to a new cipher, which we call xAES, and which is resistant against the latest related-key differential attacks found in AES. xAES has a speed benchmark close to the one of AES even in the applications which use a frequent change of the master key.
