Efficient certificateless partially blind signature scheme

Recently,several certificateless partially blind signature schemes are proposed.Unfortunately,the efficiency of these schemes remains to be further enhanced.In view of the wide application of the certificateless partially blind signatures in electronic com-merce,at first,a new certificateless partially blind signature scheme is proposed.Secondly,the proposed scheme is proved to be correct,partially blind,and unforgeable.Finally,the proposed scheme is compared with the existing ones in terms of computational cost.The results demonstrate that the proposed scheme is much more efficient than the others.Meanwhile the proposed scheme avoids the using of Map To Point hash function.
