The Research And Design Of VPN Technology Based On Secure Telecommunication

This paper aims at further research on Virtual Private Net (VPN), a currently popular information security technique. Beginning with the current situation, classification and countermeasure of the information security, then we bring forward the VPN technology. Some items of VPN will be elaborated here, following as the definition, useness, categories and solutions. The protocols that the VPN technology is concerned are also elaborated. The encryption system is also elaborated here. Finally I draw the functional module map of the implement of VPN and describe how to implement the safe telecommunication of information in detail. The research work mentioned in this paper is mainly about:(1) Research on VPN technologyThe definition, function, categories and merits of VPN; Proper application environments they are used in .The PPP protocol, the basis of PPTP and L2TP protocols, is also expounded.(2) The designation and academic analysis of VPNBased on the research of the theory of VPN technology, This paper render the map of the VPN netgate or agentserver. Integrated the network situation of enterprise or company, we elaborate the procession of how to implement the information communication and the typed designationthrough the VPN technology and also analyze the probable problem during the implement of the VPN . In the end, the conclusion and the prospect of this advanced technology' s (VPN) are also bring forward.
