Study And Application On The Model Of Data Remote Transmittal Based On CA Authentication

With the rapid development of Internet and the constant improvement of various communications equipments, more sensitive data is transmitted on Internet, therefore the security of data is becoming more important. Because of development of intelligent, data remote administration and transmittal in some enterprises, it is necessary for us to research and develop data security products for them to meet the demands of communication security in networks.Model of data remote transmittal based on CA authentication is compound by CA authentication and sensitive data security. On one hand, CA authentication is developed on the basis of OPENSSL function libraries, which provide secure and reliable channel for sensitive data between two communication terminals; On the other hand, sensitive data in server database is encoded by fields, which keep invisibility for non-correlation persons. The model, on extent, can keep sensitive data safe in most enterprises.In the dissertation, importance of data transmittal and database security are illustrated, the customer requisite analysis and the entire design are elaborated as well. The whole system is divided into four modules: Client Authentication, SQL Resolution, Data Transmittal and synchronization backup.In addition, the implementation of Client Authentication, SQL Resolution and synchronization backup is elucidated, and how to implement such functions as client certificate requisition, client validation, SQL resolution and recombination was granted more emphasis.Finally, the application of the Model of data remote transmittal based on CA authentication in Aerotech Manufacture Corporation Quality Control System is illustrated in the dissertation.
