The xor–encrypt–xor ( XEX) is a (tweakable) mode of operation of a block cipher. In tweaked-codebook mode with ciphertext stealing ( XTS mode ), it is one of the more popular modes of operation for whole-disk encryption. XEX is also a common form of key whitening, and part of some smart card proposals. [1] [2]
