提出网络域数据密匙共享和准入机制,创建新型数据库密匙架构。设计了基于数据属性加密的计算机数据库安全检测工具,就数据库数据进行属性加密,重组加密文件关键序列架构,在传统CDM数据线性规划算法的基础上,引入加密文件序列信息,设计TRIE树结构,将数据序列项转换为字母ID,利用存储容器存储数据项,建立Apriority数据序列索引,并生成索引检索数据表,通过数据库扫描,对异常项进行隔离,实现数据库安全检测。仿真实验数据显示,应用上述检测工具,数据库文件误用异常检测率提高了17%,伪装攻击拦截率提高20%,可以肯定有效地提高计算机数据库信息的安全性。

In this paper,we propose a data key sharing and access mechanism in network domain,and create a new database key architecture.A computer database security detection tool based on data attribute encryption is designed.The database data is encrypted by attributes and the key sequence structure of encrypted files is reorganized.On the basis of the traditional CDM data linear programming algorithm,the encrypted file sequence information is introduced,the TRIE tree structure is designed,the data sequence items are converted to letter ID.The storage container is used to store data items,the Apriority data sequence index is established,and index retrieval data tables are generated.Through database scanning,anomaly items are isolated to achieve database security detection.The simulation results show that the application of the above-mentioned detection tools can increase the detection rate of database file misuse by 17%and the interception rate of camouflage attack by 20%.It can be confirmed that this method can effectively improve the security of computer database information.
