Design And Implementation Of Student Status Management System Based On Chaotic Database Encryption

Important data is stored in the database.In order to avoid the important data to be attacked and destroyed, we must use some methods to protect the data. Database Security has become an important question in information security.We finished the design and implementation of Student Status Management System which based on Chaotic Encryption in this article.The development environment of the article is Visual FoxPro 6.0. The Student Status Management System not only can solve the concentration and sharing of data, but also it can realize the independence and the abstraction level of data. Safety control, concurrent access control and integrity control about data are realized. The encryption of this database is based on Chaotic Encryption. The security and confidentiality of the database is guaranteed by Chaotic Encryption. The security management of the Student Status Management System is Chaotic Encryption. The method of generating key is sensitive to initial value and parameters, the erotic, the unpredictable nature and the topological attachment of chaotic sequences. We can encrypted the login password, DBF file and character string by the Chaotic Encryption algorithm by using the program code to implement the encryption algorithm in the.prg files. Chaotic encryption algorithm is introduced in the database encryption and file encryption process in order to enhance the security and confidentiality of DBMS.
