Merkle──Hellman背包密码应用的改进

The Improvement of Merkle-Hellman Knapsack Cryptosystem

本文从实用角度提出了一种Ｍｅｒｋｌｅ—Ｈｅｌｌｍａｎ背包密码的改进算法。改进后的算法，减小了加密计算复杂性，同时也保证了安全性，能适应目前广泛应用的微机网络文件系统的加密，有一定的实用价值。

The paper demonstrates the principles and algorithms of a cryptosystem based on the principles of Merkle-Hellman Knapsack cryptosystem, and narrates the design and implementation of the improved algorithm with an example.
