| 摘 要： | 超椭圆曲线密码体制(HECC)是椭圆曲线密码体制(ECC)的自然推广,但不仅仅是一种简单的推广。HECC与ECC相比有速度快、基域小的优点。而单向签名是一种只有特定的用户才能验证的数字签名方案。该文基于超椭圆曲线密码体制提出了一个单向签名方案,并分析了其安全性。与现有方案相比,本方案有一定的优势。

| Abstract: | Hyper elliptic curve cryptosystems(HECC) is a natural generalization of elliptic curve cryptosystems,but it is not only a simple generalization.HECC is faster than ECC and the basis field of HECC is smaller than ECC.Directed digital signature is a special signature scheme that must be verified by specific user.A directed digital signature based on hyper elliptic curve cryptosystems was proposed and the security was discussed.This scheme has more advantages than which has been discussed. |
