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。
Hyper dliptic curve eryptosystems （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.
