Research on network database encryption technology

At present, the security issue of large amount of computer data storage, sensitive defense data theft and tamper-proof issue has attracted people´s attention increasingly. Database system as the core component of computer information system, database files as information aggregation, and their safety will be the top priority of the information industry. The core of information security is the database security, and database encryption security is one of the core questions of database security, compared with other safety means, in comprehensive consideration of safety degree, price, use maintenance costs, upgrade cost etc., the performance-price ratio of database encryption is the highest security means. This paper on database security, has discussed the application of database file in database security strategy and the related encryption technology, encryption algorithm and encryption method and data encryption technology.
