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...

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...

This paper proposes a blockcipher mode of operation, HCTR, which is a length-preserving encryption mode. HCTR turns an n-bit blockcipher into a tweakable blockcipher that supports ...

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. Given (deterministic) ciphers E and E that can encipher messages of l and n bits, respectively, we construct a cipher E∗ = XLS[E, E] that can encipher messages of l + s...
