| 摘 要： | 给出了一个改进的背包公钥密码系统。和原系统一样，作者利用中国剩余定理 （孙子定理）构造背包，但同时将某些随机选取的秘密量加到和乘到各背包分量上（以前构造背包密码系统从未用到加法）．因而大大提高了系统安全性。

| Abstract: | This paper presents an improved public key cryptosystem based on the knapsack problem. As with original system, the knapsack is constructed on the basis of the Chinese Remainder Theorem, some randomly chosen secrets are, however, added to and multiplied by the knapsack components. (addition has never beed adopted in the design of knapsack-based cryptosystem before). In this way, the system security is much raised. |
