摘要
介绍了航空专用网络环境下对数据库进行加密的技术及实现过程。加密系统由用户验证、访问控制、加密/解密引擎和控制列表4部分组成,采用对称密钥DES加密算法,数据库中的数据经加密系统处理后成为形式上的无规则乱码。经实际测试表明,数据量没有明显增加,数据库的访问效率没有出现显著的下降,能够避免非法用户盗取或修改数据库中的数据,达到了提高数据库安全性的目的。
The encrypt technology is introduced to database as well as its process in the environment of aeronautical private network. Encrypt system consists of four parts that are user authentication, access control, encrypt/decrypt engine and control list, which adopt symmetrical DES, and data become formally ruleless code through the disposal of encrypt system in database. There is no obvious increase in data quantities while there is no obvious decrease in the accessing efficiency to database, which could avoid the steal and modification to the data in database for illegal users in order to enhance the safety of database.
