摘　　要：企业数据库中的敏感信息一旦泄露,将会给企业造成巨大的损失,直接影响企业的生存和发展。基于上述背景,设计一种基于面向对象技术的数据库外层敏感信息加密系统。该系统以一个可编程芯片为载体,在其上编写读取程序,设计一个读取模块,用于读取企业本地数据库当中的敏感信息;通过串口转换器将敏感信息转移到系统当中,以加密服务器为载体,运行基于面向对象技术的密钥生成模型,生成密钥,并运行加/解密程序,实现数据库外层敏感信息加密。结果表明:与混合加密系统、量子密钥加密系统以及改进Rossler方程加密系统相比,设计的系统应用下,产生的资源开销更低,最低资源开销占比仅为23.36%,系统性能表现更佳;敏感信息样本的明文和密文之间相关性更小,仅在3.0左右,说明所设计系统的加密效果更好,更能保证敏感信息的安全。Once the sensitive information in the enterprise database is leaked, it will cause huge losses to the enterprise and directly affect the survival and development of the enterprise. Based on the above background, a database outer sensitive information encryption system based on object-oriented technology is designed. The system takes a programmable chip as the carrier, writes the reading program on it, and designs a reading module to read the sensitive information in the local database of the enterprise;Transfer the sensitive information to the system through the serial port converter, take the encryption server as the carrier, run the key generation model based on object-oriented technology, generate the key, and run the encryption / decryption program to encrypt the sensitive information in the outer layer of the database. The results show that compared with hybrid encryption system, quantum key encryption system and improved Rossler equation encryption system, the designed system has lower resource overhead, the lowest resource overhead is only 23.36%, and the system performance is better;The correlation between plaintext and ciphertext of sensitive information samples is less, only about 3.0, which shows that the encryption effect of the designed system is better and can ensure the security of sensitive information.
