# MPolynomialSystem

## Introduction

This page's purpose is to describe the design of a MPolynomialSystem class. This class is supposed to model multivariate polynomial systems as they e.g. appear in algebraic cryptanalysis. The proposed and almost implemented design is as follows. There is a class MPolynomialSystem which models the actual polynomial system. Also there is a base class called MPolynomialSystemGenerator which is meant as a base class for specific generators for polynomial systems like AES or the Courtois Toy Cipher.
