为了解决盲签名计算过程复杂的问题,在改进椭圆曲线数字签名方案的基础上,提出了一种基于椭圆曲线数字签名的盲签名方案。新方案通过改进签名式和验证式,同时引入三个随机参数,得到了基于椭圆曲线的强盲签名方案。分析表明,新方案加快了算法的运算速度,缩短了盲签名时间,具有更好的安全性。
To overcome the computational complexity of the existing blind signature scheme,this paper presented a blind signature scheme based on elliptic curve digital signature on the basis of improved elliptic curve digital signature scheme.It got the strong blind signature through constructing the signature equation and introducing three random parameters.Analysis shows that the new scheme shortens the time and accelerates the speed for digital signature and has better security.
