摘要

对ZLW(2008)和LHMM(2009)2个匿名签名方案的分析

指出前者不具有对签名消息的可认证性

后者不能抵抗已知签名存在伪造性攻击。在分析2个方案弱点的基础上

提出一种新的匿名签名方案

该方案达到了更强的Model3安全性且计算量较小

签名过程只需要2个群G中的乘法运算

验证过程需要n+1个双线性对运算

与其他同类方案比较

提出的方案具有更优的签名计算量和更高的签名安全性。

Abstract

The security and flaw of the two anonymous signature schemes called ZLW（2008） and LHMM（2009） were analyzed

where the ZLW scheme couldn’t provide signed message verifiability and the LHMM scheme couldn’t resist on the multiple-known-signature existential forgery.A novel anonymous signature scheme was proposed that enforced the security level to Model3 security and reduced the computational cost

which only needed two multiple calculations in G in signing phase and n+1 bilinear pairing operators in verifying algorithm.
