two attacks on xia-you Group Signature
Jianhong Zhang, Jilin Wang, and Yumin Wang
Abstract
Group signature is very important primitive in cryptography. A group signature scheme allows any group member to sign on behalf of the group in an anonymous and unlinkable fashion .In case of dispute, group manager can reveal the identity of the signer. Recently, S.Xia and J.You proposed a group signature scheme based on identity with strong separability in which the revocation manager can work without the involvement of the membership manger. In this paper, we analyze the security of Xia-You group signature and indicate that two or more group members can collude to construct a valid signature and any group member can forge a valid membership certification.
