Design on unsymmetrical VPN based IPsec under Linux
Wang Li-jun · 2006
In order to solve the problem of high cost and low package transform efficiency in the environment of multiple subnets,a unsymmetrical VPN security mechanism based on IP security protocols under Linux structure was presented,which can provide integration,security,authentication and non-repudiation services at the network layer by using authenticaiton,access authority and the routing relay.Furthermore,it can decrease the system cost and increase the package transform efficiency.
