Abstract
On the basis of the efficiency and reliability feature of existing IPSec VPN systems,the architecture of an IPSec VPN gateway system on Linux newest kernel platform is presented and improved.The corresponding Linux XFRM structure and function call structural description are introduced,including XFRM framework interaction with IPSec module handling in the kernel and the VPN gateway security tunnel construction.This system uses Linux XFRM frame to combine IP process and IPSec process.Simulation results show that the new system is both feasible and effective.
