A new certificateless partially blind signature scheme is proposed and the problem of tampering the public information of certificateless partially blind signature is solved by YuDan presented,as well as the normal security model is given for certificateless paritially blind signature.The new scheme is proved to be correct,partially blind,and security under random oracle model.Finally,the new scheme does not need confidential channel between KGC and users;Meanwhile,the proposed scheme is more efficient by pre-computing the pairing e(P,P)=g as the system public parameters and avoiding the using of special MapToPoint Hash function,compared with the existing ones in terms of efficiency,The results demonstrate that the presented scheme is much more efficient than the others.
