摘　　要：针对现有的IP时间隐通道需要事前约定IP数据包的时间间隔与传输信息之间的编码方案,不能在收发过程中根据网络的传输质量进行双盲动态调整的问题,提出了一种IP时间隐通道编码方案的双盲动态调整策略。该策略通过细分网络环境,并针对不同网络环境动态选择预设的编码方案,实现了收发双方间编码方案的双盲动态调整。为了验证策略的可靠性,实现了这种可靠双盲的IP时间隐通道。实验结果表明,该策略能够较好地实现收发双方间的双盲动态调整。To solve the problems that the existing IP covert timing channel needs to make an early agreement on the encoding scheme between the information and IP packet timing interval,and cannot dynamically the double-blindly adjust the encoding scheme according to the network transmission quality in the process of sending and receiving,a double-blind dynamic adjustment strategy to negotiate IP covert timing channel encoding scheme was proposed.By segmenting the network environment and depending on the dynamic network environment,the strategy selected the default encoding scheme,and achieved double-blind dynamic adjustment of encoding scheme between sender and receiver.In order to verify the reliability of strategy,the experimental environment of covert timing channel was constructed.The results show that the proposed method can achieve double-blind dynamic adjustment between sender and receiver.
