本文首先构造了一个基于椭圆曲线的E1Gamal型广播多重数字签名方案,然后在其基础上我们设计了一个基于改进的椭圆曲线E1Gamal广播多重盲签名方案.这两个方案的安全性强、计算量小、效率高,从理论上分析能够防止系统攻击者的各种攻击.
This paper constructs a system based on elliptic curve type E1Gamal broadcasting digital muhisignature scheme;Then, we design a based on improved elliptic curve E1Gamal broadcast multiple blind signature scheme. The two programmes are strong safety, small amount of calculation, and high efficiency, from theoretic analysis they are able to prevent the attacker g attack system.
