Abstract


VPN (Virtual Private Network) refers to the virtual subnet logical physically distributed in different locations in the network are connected through a common backbone network , which provides a safe, trusted communication channel for the two sides to use . IPSec high security to ensure the secure transmission of information on the Internet . This paper first introduces the theoretical knowledge of the VPN , followed by a more detailed description of the IPSec protocol . IPSec part of the module and then focus on the analysis , and proposed improvements : If the signature authentication method improved ; improvements in the anti-replay attack ; improvement denial of service attacks . Then a detailed analysis of defects exist in the IPSec implementation , and proposed improvements for the problem : First, using the GRE Over IPSec technology to effectively solve the multi-protocol analysis ; Second IPSec VPN network structure proposed dual the central gateway Xingxingjiegou to replace the traditional the pure mesh or star network, and to strengthen the stability and flexibility of the network . Finally, previous improvements , given the specific networking solutions and improvement program is given in the practical application instance .
