One New Research about IPSec Communication Based on HTTP Tunnel

Abstract

This paper first discusses the classic methods of covert communication to traverse the firewall devices which control the network communication. And based on the analysis of IPSec protocol architecture, that the worse of network compatibility of IPSec is got. So the new IPSec over HTTP protocol based on IPSec tunnel and HTTP tunnel is exposed including its structure and procedure. The soft structure of FreeSWAN is improved and the performance test data are presented in order to validate this new protocol. Finally, the performance of the new system is analyzed detailedly
