| 摘 要： | 背包公钥密码算法是比较热门的加密算法之一,目前仍有很多密码研究者在研究背包公钥密码的改进算法。文献[1]提出了两个改进的背包公钥密码方案,本文对这些改进算法进行了安全性分析,并就其中一个方案进行了格规约攻击。通过计算实验说明这种改进之后的背包公钥密码算法仍然是不安全的。

| Abstract: | Knapsack public-key cipher algorithm is one of popular encryption algorithms, there are also many people research the knapsack public-key cipher algorithm recently Document [1] puts forward two improved knapsack public-key cipher scheme, in this paper, there is a security analysis of the improved algorithm, and use the lattice code against one of the scheme The calculation results prove that the improved algorithm is still not safe . |
