面向敏感区域的密文数据库存储加密方法

Encryption Method of Ciphertext Database Storage for Sensitive Areas

由于现有存储加密方法不能恢复完整的明文,为此提出面向敏感区域的密文数据库存储加密方法。首先,设计适合面向敏感区域的密文数据库,运用密文检索技术加密明文数据后上传至服务器。其次,初始化密钥,按照数据属性进行加密后与数据域绑定。最后,进行实验分析。实验结果表明,实验组的最大明文存储加密速度达到3000 m/s,优于对照组,能够完整恢复出密文,具有较好的应用效果。

Due to the inability of existing storage encryption methods to recover complete plaintext,a sensitive area oriented ciphertext database storage encryption method is proposed.Firstly,design a ciphertext database suitable for sensitive areas,encrypt plaintext data using ciphertext retrieval technology,and upload it to the server.Secondly,initialize the key,encrypt it according to data properties,and bind it to the data domain.Finally,conduct experimental analysis.The experimental results show that the maximum plaintext storage encryption speed of the experimental group reaches 3000 m/s,which is better than the control group and can fully recover the ciphertext,with good application effects.
