Abstract

Several new groupsignature schemes have been proposed in recent years. In addition, several applications for group signatures (including electronic cash) have been suggested.

A new cash scheme based on a recent groupsignature by Ateniese, Camenisch, Joye and Tsudik is presented. Its construction uses a general framework suitable for a number of groupsignature schemes. We also identify the challenges faced by such schemes.
