Ying Li, Guifen Zhao, Tong Liu · 2009
In order to improve the data security over network and provide more effective data protection product, this paper introduces a network data protection system based on combined symmetric key. The system takes into account four main aspects in data protection, including identity authentication, encryption transmission, access controls and encryption storage. The solution combines four aspects into a whole secure system. Meanwhile, hardware equipment and combined symmetric key encryption technique are applied to encrypt the information. Consequently, network data security would be enhanced.
