Tweakable enciphering schemes are length preserving block cipher modes of operation that provide a strong pseudo-random permutation. It has been suggested that these schemes can b...
Abstract. Tweakable enciphering schemes are a certain type of blockcipher mode of operation which provide security in the sense of a strong pseudo-random permutation. It has been p...
We describe a block-cipher mode of operation, CMC, that turns an n-bit block cipher into a tweakable enciphering scheme that acts on strings of mn bits, where m ≥ 2. When the und...
