WebAug 17, 2002 · We propose a new cryptographic primitive, the "tweakable block cipher." Such a cipher has not only the usual inputs - message and cryptographic key - but also a third input, the "tweak." The tweak serves much the same purpose that an initialization vector does for CBC mode or that a nonce does for OCB mode. Our proposal thus brings this … Webstorage. XTS-AES is a tweakable block cipher that acts on data units of 128 bits or more and uses the AES block cipher as a subroutine. The key material for XTS-AES consists of a data encryption key (used by the AES block cipher) as well as a “tweak key” that is used to incorporate the logical position of the data block into the encryption.
