摘　　要：为保障计算机网络隐私数据加密效果,本文提出了基于改进DES算法的计算机网络隐私数据加密方法研究。分析了高维数据加密困难、密钥长度过短导致暴力破解等问题;运用主成分分析法(PCA)提取计算机网络数据的特征向量,完成数据降维;依据提取的特征向量构建超平面分类器模型,并通过调整参数优化其性能,自动判断数据是否包含敏感信息;引入哈希函数对DES算法进行改进,通过延长密钥长度来增强其加密强度,并采用改进后的算法对挖掘出的隐私数据进行加密,以实现网络隐私数据加密设计。实验结果表明,该方法应用于计算机网络隐私数据加密时,不仅展现出了良好的加密效果,还显著提高了加密效率,应用效果较好。To ensure the encryption effect of privacy data in computer networks,a research on computer network privacy data encryption method based on improved DES algorithm is proposed in this article.Analysis addresses issues such as difficulty in encrypting high-dimensional data and brute force cracking caused by excessively short key lengths;By using principal component analysis(PCA)to extract feature vectors from computer network data,data dimensionality reduction is achieved;Construct a hyperplane classifier model based on the extracted feature vectors,and optimize its performance by adjusting parameters to automatically determine whether the data contains sensitive information;Introducing a hash function to improve the DES algorithm,enhancing its encryption strength by extending the key length,and using the improved algorithm to encrypt the mined private data,in order to achieve network privacy data encryption design.The experimental results show that this method not only demonstrates good encryption performance when applied to privacy data encryption in computer networks,but also significantly improves encryption efficiency,and the application effect is good.
