Title:
A Note on Masking Generic Boolean Functions
Authors: Lauren De Meyer, Felix Wegener, Amir Moradi
Abstract:Masking is a popular countermeasure to protect cryptographic implementations against side-channel attacks (SCA). In the literature, a myriad of proposals of masking schemes can be found. They are typically defined by a masked multiplication, since this can serve as a basic building block for any nonlinear algorithm. However, when masking generic Boolean functions of algebraic degree t, it is very inefficient to construct the implementation from masked multiplications only. Further, it is not immediately clear from the description of a masked multiplication, how to efficiently implement a masked Boolean function. In this work, we fill this gap in the literature with a detailed description and investigation of a generic masking methodology for Boolean functions of any degree t at any security order d.
