摘　　要：在介绍环Zn上广义圆锥曲线的阶和基点、离散对数问题、明文嵌入与译码算法的基础上,研究多重数字签名中的广播多重数字签名。该方案的安全性是基于大整数分解的困难问题和离散对数问题,而且其在点的计算、明文嵌入都较容易实现,还能抵抗Pohlig-Hellman攻击以及小指数攻击和Wiener攻击。On basis of the introduction of the order and the base point on the generalized conic curve over Zo, the discrete a log- rithm problem, plaintext embedding and decoding algorithm, this paper discusses a broadcasting multi-signature scheme. The security of the scheme is based on the factoring and discrete logarithms simultaneously. It can not only speed up the inverse operation and embed plaintext easier, but also resist Pohlig-Hellman＇ s attack and Wiener＇ s attack.
