摘　　要：首先设计了一种新的基于椭圆曲线的数字签名方案,然后基于此给出了有序多重数字签名方案和广播多重数字签名方案。该方案的安全性能建立在椭圆曲线之上,所以其安全性更好,同时具有计算量小,处理速度快等特点,因此在带宽要求低和无线网络领域中具有广泛的应用前景。A new digital signature scheme based on elliptic curve cryptosystem was proposed. With this scheme, a new sequential digital multisignature and a new broadcasting digital mulitisignature were presented in detail. The security of all these schemes is based on the problem of elliptic curve discrete logarithm. So the schemes have low computational load and higher speed of implementation and etc, especially can be used in the situation as low bandwidth and wireless network.
