文章针对目前的各种代理签名方案所存在的无法实现对代理签名者的代理签名权力进行全面、完整、可靠地控制的问题,提出了一种具有限制代理签名者行使代理签名权力的基于超椭圆曲线离散对数问题的新型可控代理签名方案XHCLPS,同时对这一方案的复杂性和安全性进行了分析。新方案不仅推广和丰富了代理签名的研究成果和应用范围,而且也扩展了超椭圆曲线密码体系的功能,为信息安全问题的解决提供了新的密码学方法。
Today,all the known proxy digital signature schemes has the same problem that can't provide the overall, complete,reliable control ability on the stretch of proxy digital signature power.In this paper,we advance a new proxy digital signature scheme based on hyperelliptic curve discrete algorithmic problems which is called as Xiao's Hyperelliptic Curve Limited Proxy Signature.It has the ability to provide the overall,reliable control on the using of proxy digital signature power.Further more,we also analyze the new scheme's computation complexity and security problem.The new scheme,which is an extension of elliptic curve cryptosystems,is beneficial for the study on the domain for the proxy digitial signature.
