基于DES数据加密算法的计算机信息系统保密技术

Computer Information System Security Technology Based on DES Data Encryption Algorithm

传统的防火墙技术虽然可以加密信息,但效率较低,因此设计基于DES数据加密算法的计算机信息系统保密技术。该技术能够搜索计算机中的保密信息,在此基础上基于DES数据加密算法进行数据加密,管理计算机信息密钥,从而实现计算机信息保密。实验结果表明:设计的计算机信息保密技术在面临大量数据信息时仍能保持良好的保密功能,因此具有一定的应用价值。

Although the traditional firewall technology can encrypt information,its efficiency is low.Therefore,the security technology of computer information system based on DES data encryption algorithm is designed.This technology can search the confidential information in the computer,encrypt the data based on DES data encryption algorithm,and manage the computer information key,so as to realize the confidentiality of computer information.The experimental results show that the designed computer information security technology can still maintain a good security function in the face of a large amount of data information,so it has a certain application value.
