摘要

In response to needs of disk encryption standardization bodies, we provide the first tweakable ciphers Hutt are proven to securely encipher their own keys. We provide both a narrow block design StE and a wideblock design EtE. Our proofs assume only standard PRP-CCA security of the underlying tweakable ciphers.
