We perform a special number field sieve discrete logarithm computation in a 1024-bit prime field. To our knowledge, this is the first kilobit-sized discrete logarithm computation ever reported for prime fields. This computation took a little over two months of calendar time on an academic cluster using the open-source CADO-NFS software.

This work proposes a new method to find the special number field sieve(SNFS) polynomial pair of a given prime, and recommends a simple ad-hoc detection of the trapdoor before doing the general numberField sieve (GNFS) to a prime $p$.

It is shown that this modification of an algorithm for finding discrete logarithms over the field GF(p) (p is a prime number) gives the best estimate at the present time of the complexity of finding discrete logs over finite prime fields which coincides with the best known estimate of the difficulty of factoring integers obtained by D. Coppersmith.
