Abstract
A method for verifying an electronic signature is described including determining a residue class given by the signature; determining an integer having the residue class; determining a field element of a finite field such that the field element corresponds to the integer according to a predetermined mapping of the finite field to the set of integers; determining whether the field element fulfills a predetermined criterion and deciding whether the signature is valid based on whether the field element fulfills the predetermined criterion.
