摘　　要：针对传统签名方案中验证者的验证权限是相同的缺点,文中基于Jia方案提出一种基于椭圆曲线的链式授权签名方案。首先,本方案有效地提高了系统密钥强度,降低内存和带宽等系统资源占用率,提高了运行效率。其次,利用盲签名技术解决了Jia方案一次授权签名验证之后签名者公钥暴露问题,实现了在不频繁改变签名者私钥的情况下实现多次授权签名验证。由于本方案基于椭圆曲线加密体制,所以方案适用于电子政务和电子商务等移动通信终端设备。To overcome the shortcoming of Jia＇s scheme,a new chain verification digital signature scheme based on the elliptic curve cryptography is proposed, which can avoid the equal verifying right of the verifiers in the conventional schemes.First,effectively increase key strength,reduce system resources occupancy rates of the memory and bandwidth and so on,enhance the operating efficiency.Next,using the blind signature technology to solve the problems in Jia＇s scheme caused by the subscriber＇s public key will be known after once authorization verification signature.This scheme can realize many times authorization signature but need not change the subscriber＇s private key frequently.Because this scheme based on elliptic curve cryptosystem,so it is suitable for electronic government and electronic commerce mobile communication terminal device.
