We introduce C, a practical provably secure block cipher with a slow key schedule. C is
based on the same structure as AES but uses independent random substitution boxes …

We propose a new mode of operation, enciphered CBC, for domain extension of length-
preserving functions (like block ciphers), which is a variation on the popular CBC mode of …

Recently, Jutla suggested two new modes of operation for block ciphers. These modes build
on traditional CBC and ECB modes, respectively, but add to them masking of the outputs …

Abstract The cipher CTC (Courtois Toy Cipher) has been designed to demonstrate that it is
possible to break on a PC a block cipher with good diffusion and very small number of …

Block ciphers are usually made from one general scheme in which we plug round functions.
For analyzing the security, it is important to study the intrinsic security provided by the …

In this note we dene small scale variants of the block cipher present [1]. The main reason for
this is that the running time of some recent attacks (eg [2, 3]) remain unclear as they are …

This paper extends the provably-secure blockcipher construction proposed at FSE 2009 by
Minematsu. Unlike the classical Luby-Rackoff cipher and its variants, the scheme is based …

An important component of an iterated block cipher is the key schedule. In this paper, we
consider iterated block ciphers with a key schedule algorithm described by a recurrence …

In this document, we describe the design of a new family of block ciphers, named FOX. The
main goals of this design, besides a very high security level, are a large implementation …
