| 摘 要： | 文中给出基于背包和有限域上圆锥曲线相结合的代理签名方案，并具体分析了该代理签名方案的安全性是基于求解有限域上圆锥曲线的离散对数问题和求解变形的背包问题，只有这两个问题都被攻破了，才能破解该代理签名方案，所以该代理签名方案具有很强的安全性。

| Abstract: | This gives a new proxy signature scheme based on knapsack problem and conic curves public-key cryptosystem. The security of this proxy scheme is based on conic curves discrete logarithms problem over finite field and specific knapsack problem. Only these two problems are solved, could this scheme be broken. Therefore, this proxy Signature scheme is of very strong security. |
