Untraceability of Two Group Signature Schemes
Zhengjun Cao
Abstract
A group signature scheme allows a group member of a given group to sign messages on behalf of the group in an anonymous fashion. In case of a dispute, however, a designated group manager can reveal the signer of a valid group signature. In the paper, we show the untraceability of two group signatures in [1, 5] by new and very simple attacks. Although those flaws, such as, forgeability, untraceability and linkability have been shown in [2, 7, 8, 9], we should point out that our attacks are more simple.
