Online Ciphers from Tweakable Blockciphers
Abstract. Online ciphers are deterministic length-preserving permutations EK : ({0, 1}n )+ → ({0, 1}n )+ where the i-th block of ciphertext depends only on the first i blocks of...

On Tweaking Luby-Rackoff Blockciphers
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...

A Domain Extender for the Ideal Cipher
We describe the first domain extender for ideal ciphers, i.e. we show a construction that is indifferentiable from a 2n-bit ideal cipher, given a n-bit ideal cipher. Our construc...

A Modular Design for Hash Functions: Towards Making the Mix-Compress-Mix Approach Practical
The design of cryptographic hash functions is a very complex and failure-prone process. For this reason, this paper puts forward a completely modular and fault-tolerant approach to...
