Loosening the KNOT
Abstract. In this paper, we present differential attacks on the selfsynchronizing stream cipher KNOT. Our best attack recovers 96 bits of the secret key with time complexity of 26...

On Plateaued Functions and Their Constructions
We use the notion of covering sequence, introduced by C. Carlet and Y. Tarannikov, to give a simple characterization of bent functions. We extend it into a characterization of plat...

The Security of "One-Block-to-Many" Modes of Operation
In this paper, we investigate the security, in the Luby-Rackoff security paradigm, of blockcipher modes of operation allowing to expand a one-block input into a longer t-block ou...

Block Ciphers and Systems of Quadratic Equations
Abstract. In this paper we compare systems of multivariate polynomials, which completely define the block ciphers Khazad, Misty1, Kasumi, Camellia, Rijndael and Serpent in the vie...

Analysis of Involutional Ciphers: Khazad and Anubis
In this paper we study structural properties of SPN ciphers in which both the S-boxes and the affine layers are involutions. We apply our observations to the recently designed Rijn...

Helix: Fast Encryption and Authentication in a Single Cryptographic Primitive
Abstract. Helix is a high-speed stream cipher with a built-in MAC functionality. On a Pentium II CPU it is about twice as fast as Rijndael or Twofish, and comparable in speed to R...
