基于文件型嵌入式数据库的加密研究

he embedded database based on file has a great disadvantage on safety. You can get the information easily, if you gain the database file. Especially when the database file is the database of Web server, it has the danger to be downloaded randomly if it can be accessed by the Web application. This paper gives a method to encrypt the database file that transfers the information of the database file into the data which can not to be read directly after the research of the encryption method and the data structure.
