摘要
网络隐蔽时间信道具有较高的抗检测性能,受到了国内外的高度关注。载体和调制时间间隔的选择直接影响着信道性能。当前的研究普遍存在载体单一和时间间隔选择不合理的问题,提出了一种自适应参数选择隐蔽时间信道的设计方案。通过分析通信双方的网络流量,自适应的选择载体和设定调制时间间隔。通过与传统隐蔽时间信道设计方案实验对比,发现该方案具有更优的性能。
As network covert timing channel with highly detection resistance ,it has been highly concerned at home and abroad .The selection of carrier and timing interval directly affects the performance of the channel .A new covert timing channel is proposed ,which is based on the adaptive parameter selection .The selection of carrier and time interval are based on the network traffic between the two sides of communicator .Compared with the traditional covert timing channel ,it has been proved to be a better one .
