How to convert any ID-based Signature Schemes
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.
