Discrete Logarithms in $GF ( P )$ Using the Number Field Sieve

Abstract: Recently, several algorithms using number field sieves have been given to factor a number n in heuristic expected time Ln[1/3; c], wherefor n → ∞. In this paper we present an algorithm to solve the discrete logarithm problem for GF (p) with heuristic expected running time Lp[1/3; 3 2/3 ]. For numbers of a special form, there is an asymptotically slower but more practical version of the algorithm.

“…In solving the DLP in GF(3 6n ), these two variants of the FFS have the same asymptotic complexity, but the new variant was expected more efficient than the earlier one in some extension degree n. By our experiment result, we confirmed this forecast when the extension degree n = 19, 61. Moreover, with our implementations, we computed [10,17]. † JLSV06-NFS: NFS in the medium prime case [19].…”

“…First, however, we focus on the DL problem in a subgroup γ of prime order ω of the multiplicative group GF(p t ) * of an extension field GF(p t ) of GF(p) for a fixed t. There are two approaches to this problem (cf. [1], [5], [9], [11], [16], [19], [21]): one can either attack the multiplicative group or one can attack the subgroup. For the first attack the best known method is the Discrete Logarithm variant of the Number Field Sieve.…”

“…Now suppose we want to solve the ECDL problem for a given prime p by using Mestre's method to lift E/ p to a curve E/É of moderately large rank. Looking at the Heuristic Bound (10), in order to have a reasonable chance of lifting a point of E( p ) to a point of E(É) of height at most B, we need N (E, B) fairly close to p, say N (E, B) ≥ p/2 10 . Then (10) and (11) give us the lower bound log B ≥ r log(p 11.93 r 0.26r ) 20πe…”
