中文摘要：

由于近来提出的几个无证书部分盲签名方案的效率还有待进一步提高，鉴于无证书部分盲签名在电子商务领域的广阔应用前景，构造了一个新的无证书部分盲签名方案。分析了该签名方案的正确性、部分盲性和不可伪造性，并对该方案与现存方案的计算代价进行了比较。比较结果表明，该方案比现有其它方案都要高效，同时该方案还避免了使用Map To Point哈希函数。

英文摘要：

Recently, several certificateless partially blind signature schemes are proposed. Unforttmately, the efficiency of these schemes remains to be further enhanced. In view of the wide application of the certificateless partially blind signatures in electronic commerce, 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.
