摘　　要：超椭圆曲线密码体制(HECC)是以超椭圆曲线离散对数问题的难解性为基础的,相对于其他密码体制而言,具有安全性高、操作数短等优点。文中设计了一种基于超椭圆曲线密码体制的盲数字签名方案,方案中提出了对消息盲化的方法。该方案具有很高的安全性,非法用户很难通过截获的消息来获取明消息,因为盲化是建立在离散对数问题上的。The hyperelliptic curve cryptosystem is based on the hyperelliptic curve discrete logarithm problem, and has the higher safety and the shorter operands as compared to other cryptosystems. This paper proposes a blind signature scheme based on the hyperelliptic curve cryptosystem. For the blind method is based on discrete logarithm problem, it is difficult for unauthorized users to analyze the plaintext without blind factor. Therefore, it is of a safety.
