Abstract. Tweakable blockciphers, first formalized by Liskov, Rivest, and Wagner [13], are blockciphers with an additional input, the tweak, which allows for variability. An open p...

The Feistel-network is a popular structure underlying many block-ciphers where the cipher is constructed from many simpler rounds, each defined by some function which is derived fr...

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...

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 ...

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...
