Security analysis of group signature scheme based on RSA
Yilin Zhang · Computer Engineering and Applications Journal · 2010
Cryptanalysis of a group signature scheme based on RSA shows that it exists follow security flaws:(1)group centre can forge any group member's signature on condition that the member's public key is kept in the PKSL;(2)group member can generate a group signature that it can not be traced;(3)either group member or the signature verifier can announce key on behalf of the group centre;(4)group manager can frame up any group member if member's key is kept in the PKSL.
