![On Exact Algebraic [Non-]Immunity of S-Boxes Based on Power Functions](https://www.sciweavers.org/files/imagecache/thumbnail/default/content.jpg "On Exact Algebraic [Non-]Immunity of S-Boxes Based on Power Functions")
In this paper we are interested in algebraic immunity of several well known highly-nonlinear vectorial Boolean functions (or Sboxes), designed for block and stream ciphers. Unfortu...
