Key Recovery Scheme of IPSec Based on Subliminal Channel
Dawu Gu · Jisuanji gongcheng · 2008
The key recovery schemes available usually use the method of adding a key recovery field at the end of the protocol packet. So the intruder can easily distinguish the data packet with key recovery functions from the others and filtrate them in order to prevent key recovery. The paper describes an IPSec key recovery scheme based on subliminal channel. The scheme is easy to implement,and the packets are not filterable which can avoid the intruder’s filtration. This scheme provides efficient network monitor and control.
