Research And Implementation Of An Encrypted Computer Communication System Based On Secure FTP

With the constant development and popularization of Internet,it has become a primary means of information transmission in government and enterprises. However, plain in the form of transmission of sensitive information and lack of effective identity authentication and access control mechanisms will be caused great damage and harm to enterprises and country.FTP (File Transfer Protocol) is mainly used to file transfer on the network with the advantages of high transmission efficiency, E-mail has been widely used to operate convenience features. Based on the transmission mode of FTP and operate convenience of e-mail and encryption technology, an encrypted computer communications system based-on secure FTP is proposed in the paper. The system provide functions of the admission office systems text documents,warning,log inquiries and encryption, and realization of access for transmit sensitive data of government office.In this paper, the main contents are : design and implementation of FTP security solution, the realization of FTP Server and Client, the design of FTP data communications management module and FTP monitor module. FTP security solutions using encryption software and hardware encryption in two ways.
