Boolean functions with restricted input and their robustness; application to the FLIP cipher
Claude Carlet and Pierrick Méaux and Yann Rotella
Abstract
We study the main cryptographic features of Boolean functions (balancedness, nonlinearity, algebraic immunity) when, for a given number $n$ of variables, the input to these functions is restricted to some subset $E$ of $\mathbb{F}_2^n$. We study in particular the case when $E$ equals the set of vectors of fixed Hamming weight, which plays a role in the FLIP stream cipher and we study the robustness of the Boolean function in this cipher.
