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 pnp^n in expected time (pn)2log2(n)+O(1)(pn)^{2\log_2(n) + O(1)}.
