Abstract:
Illegal communications by covert channel in network become an important way to threaten the network security. The paper gives thegeneral way for constructing a covert channel and brings a channel based on HTTP protocol to get better secrecy, anti-shielding property, as theopinion of attacker.
摘要： 网络数据流中利用隐蔽通道来进行非法通信已逐渐成为威胁网络信息安全的一种重要手段。该文从攻击者的角度研究隐蔽通道,针对利用低层协议构建隐蔽通道的不足,提出了使用HTTP协议构建隐蔽通道的方法,有效地提高了隐蔽通道的隐蔽性、抗屏蔽性。
