Abstract

We describe in this article how we have been able to extend the record for computationsof discrete logarithmsin characteristic 2 from the previousrecord over F2503 to a newer mark of F2607 , using Coppersmith's algorithm. This has been made possible by several practical improvementsto the algorithm. Although the computationsha ve been carried out on fairly standard hardware, our opinion is that we are nearing the current limitsof the manageable sizesfor thisalgorithm, and that going substantially further will require deeper improvements to the method.
