Cryptographic hash functions are often built on block ciphers in order to reduce the security of the hash to that of the cipher, and to minimize the hardware size. Proven secure co...

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...

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...

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, th...

Liskov, Rivest and Wagner formalized the tweakable blockcipher (TBC) primitive at CRYPTO’02. The typical recipe for instantiating a TBC is to start with a blockcipher, and then b...
