ID-based CES threshold signature
基于身份的可截取门限签名方案

To improve the efficiency of multiparty interaction and reduce the problem of multiple signature and communication, an ID-based CES threshold signature based on the bilinear pairing was presented. Effective threshold signature recovery and signature extraction of the proposed signature scheme can be realized without more interaction with the signer. The proposed signature scheme ensures the efficiency and robustness of signature, and can defend existential forgery on adaptively chosen message and ID attack in the random oracle model.
