Discrete logarithms in quasi-polynomial time in finite fields of fixed characteristic (1906.10668v2)

Abstract: We prove that the discrete logarithm problem can be solved in quasi-polynomial expected time in the multiplicative group of finite fields of fixed characteristic. More generally, we prove that it can be solved in the field of cardinality $p^n$ in expected time $(pn)^{2\log_2(n) + O(1)}$.
