An Effective Method to Implement Group Signature with Revocation
Abstract: This paper presents an effective method to integrate the revocation mechanism into
some group signature schemes that are based on the strong RSA assumption. The mechanism enables
the group manager to either update a group member's certificates, or revoke a group member.
More specifically, a generic method has been proposed for the protocols of sign, verify, and revocation.
We demonstrate the effectiveness of the method by applying it to
a well known group signature scheme. The new construction has better performance while
enjoying an efficient revocation mechanism.
