Till Stegers Faugère's F5 Algorithm Revisited Abstract: Gröbner bases are a common tool to solve systems of polynomial equations in several variables, such as those arising in algebraic attacks on crypto systems. In this talk, we outline Faugère's F5 algorithm for computing Gröbner bases and describe the novel optimizations introduced by Faugère to avoid unnecessary computations. We report on our experiences implementing F5 and briefly suggest how to combine F5 and its predecessor F4. |
