Anonymous ID Signature Scheme with Provable Identity
Xiaodong Liu, Xiang Gao · 2008
In this paper, a user can login a certain system with a anonymous ID generated by Key Generate Center (KGC) and perform data signing operation. Other Members in the group, even KGC, can not reveal the real identity of the user from his anonymous ID. When doubt appears, the user can submit evidence information to KGC to prove his legality. The scheme is constructed from ID-based Blind Parameters Signature Scheme and Short Signature Scheme. Last, describes analysis on security of the scheme.
