BISON - Instantiating the Whitened Swap-Or-Not Construction

Anne Canteaut and Virginie Lallemand and Gregor Leander and Patrick Neumann and Friedrich Wiemer

Abstract: We give the first practical instance – BISON – of the Whitened Swap-Or-Not construction. After clarifying inherent limitations of the construction, we point out that this way of building block ciphers allows easy and very strong arguments against differential attacks.
