| 摘 要： | 根据批量签名的思想，将 Waters 数字签名方案批量化，进而构造可截取签名。所构造的方案是Steinfeld、Bull、Zheng ( ICISC 2001) 提出的RSAProd方案的改进，以较长的截取签名长度为代价节省整体的运算时间，并证明所构造方案在适应性选择消息攻击下具有不可伪造性和隐私性。

| Abstract: | The Waters scheme was transformed into the content extraction signature scheme at the bridge of the thought from the batch signature scheme.The proposed scheme is improved by the RSAProd scheme,presented by Steinfeld,Bull,Zheng (ICISC 2001).The operation time is saved in every stage at the slight sacrifice of the length of extraction signatures.The security was proved that the proposed scheme is existentially unforgeable under chosen message attacks while the privacy is maintained. |
