摘　　要：由于椭圆曲线密码具有良好的性质,基于椭圆曲线的盲签名引起了人们的普遍关注。利用仿射变换对基于椭圆曲线的Schnorr签名构造盲签名方案,得到了一系列盲签名方案。通过对这些盲签名方案进一步分析得知,当随机参数为3个时,得到基于椭圆曲线的Schnorr强盲签名方案;当随机参数少于3个时,得到基于椭圆曲线的Schnorr弱盲签名方案。As elliptic curve cryptography has better characters, the blind signature based on elliptic curve attracts the people. Through affine transform, a series ofschnorr blind signature schemes based on elliptic curve are got. Through the analysis to these blind signature schemes, when the blind transform has three random variables, the schemes are schnorr strong blind signature schemes. When the blind transform has less random variables than three, the schemes are schnorr weak blind signature schemes.
