A group signature allows a group member to sign messages anonymously on behalf of the group .However , in the case of a dispute , the identity of a signatures originator can be revealed by the group manager .This work allows the group manager to let several proxies , such as an identity revocation committee, share the ability of revealing the identity of the group member by sharing the members certificate
Key words： group signature; identity opening committee; traceability
