| 摘 要： | RSA和背包公钥密码算法都是经典的加密算法，目前仍有很多密码研究者在研究它们的改进算法. 王茜等作者将两者结合起来设计了一个新的密码方案，将RSA用到了背包密码体制中. 对这一新方案进行了安全性分析，从三个角度对这一方案进行了分析说明，并通过格规约攻击计算实验来验证，最终说明这种改进之后的公钥密码算法仍然是不安全的.

| Abstract: | RSA and Knapsack public-key cipher algorithm are classical encryption algorithms. There are also many people researches about the improvement of them recently. Wang Qian created a knapsack public-key cipher scheme based on RSA. There are a security analysis of the improved algorithm and a analysis form three angles of the scheme in this paper. Finally, we will use the calculation results of the lattice code against to prove that the improved algorithm is still not safe. |

| Keywords: | knapsack public-key cipher improved algorithm security analysis lattice reduction |
