A General Construction of Tweakable Block Ciphers and Different Modes of Operations
This work builds on earlier work by Rogaway at Asiacrypt 2004 on tweakable block cipher (TBC) and modes of operations. Our first contribution is to generalize Rogaway's TBC co...

A Tweakable Enciphering Mode
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...

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...

Cryptanalysis of the EMD Mode of Operation
Abstract. In this paper, we study the security of the Encrypt-MaskDecrypt mode of operation, also called EMD, which was recently proposed for applications such as disk-sector encry...

Pseudo-random functions and parallelizable modes of operations of a block cipher
This paper considers the construction and analysis of pseudo-random functions (PRFs) with specific reference to modes of operations of a block cipher. In the context of message aut...
