New research about covering communication based on protocol of IPSec over DNS
一种新的基于DNS协议的IPSec隐蔽通信研究

By discussing covering communication technology and the poor compatibility of IPSec protocol network, the paper proposed a new VPN protocol of IPSec over DNS based on IPSec tunnel and DNS tunnel, and analyzed its structure and procedure. The performance test data show that it provides a safer network security solution with the integration of these two technologies.
