Design and application of computer database security detection tool based on attribute encryption

Abstract： 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.
