How to convert any ID-based Signature Schemes

Claude Castelluccia

Abstract: This paper describes how any Identity Based Signature schemes can be used to implement a Group Signature scheme. The performance of the generated Group Signature scheme is similar to the performance of the underlying ID-based Signature scheme. This makes our proposal very attractive since most of existing group signature schemes that have been proposed so far are grossly inefficient. In contrast, ID-based signature schemes can be very efficient especially if they use elliptic curves and pairing.
