摘要
多重数字签名的概念及方案的提出大大拓宽了数字签名的应用范围。基于椭圆曲线密码体制,提出了一种以椭圆曲线为基础的广播型多重数字签名方案。该方案研究了如何充分发挥椭圆曲线密码密钥长度短、效率高、安全强度大的优势来解决多重数字签名的缺陷,该方案可以有效地抵抗多种攻击,安全性高。
With the appearance of the signature has been greatly enlarged concept and scheme of the digital multi - signature, the scope of digital A broadcasting multi -signature scheme based on Elliptic Curves was presented. This scheme examines how to bring into full play the short length of key, high efficiency, and security of the Elliptic Curve Cryptosystem to solve the problems in Multi - signature. This scheme can effectively resist attacks and has high security.
