中文摘要: 网络隐蔽信道是将窃取的机密信息隐藏在正常的网络传输协议中的一种通信方法. 由于网络时间隐蔽信道不修改网络数据包的内容, 因此更加难以检测和限制, 从而具有更大的威胁. 提出一种新的基于Web访问模型的网络时间隐蔽信道, 恶意用户通过规律性的访问Web服务器实现机密信息传输; 实现了该网络隐蔽信道原型, 并给出了信道的性能分析结果.
Abstract:Network covert channel is a transmission scheme which hides the confidential information to normal network channel. Network covert timing channel does not modify the network packets, therefore it is more difficult to detect and more dangerous. This paper presents a new network covert timing channel based on Web access model. Malicious users transfer the confidential information by regularly access the Web server in this channel. We implement the prototype of the covert channel, and analyze the channel performance.
