Network Database Encryption Technology Research And Application

As the data storage "warehouse" and the security of the database in the computer information security will undoubtedly occupy a pivotal position. And data encryption on the database, the database of information security is to protect one of the important means. So the encryption technology in the database application of the research has a very important practical significance. Most of the past and existing database encryption method is single-level encryption, the paper proposes a multi-level encryption methods. This is different from the existing encryption method of new ideas.First, this database encryption technology and password carried out detailed technical studies, mainly from the encryption and decryption and encryption level of the typical process of cryptographic techniques to study.Secondly, the paper in cryptography and database encryption technology on the basis of the encryption models, key management and encryption protection for the research, database attacks against popular methods in detail, and made a solution.Finally, the design of a secondary encryption method, the first level of the user's password database using MD5 encryption, the second-level storage in the database of passwords table to make another MD5 encryption. This encryption method can increase the database password security.The implementation of the system in order to Eclipse3.1 Tomcat 5.0 and development tools in the development process by implementing the ideas of object-oriented programming. System is divided into a number of functional modules, the modules organic combination of an over all encryption systems. Finally, the article was analyzed, and the future.
