Mobile Platform Terminal Covert Channel Data Transmission Synchronization Method

为提升移动平台终端数据传输吞吐量、降低传输时的平均延迟,提出了移动平台终端隐蔽信道数据传输同步方法。将私密数据调整为人工噪声,同时将该人工噪声引入到正常信号中实现传输,完成移动平台终端隐蔽信道设计;利用时钟同步调度方法优化单隐蔽信道传输,通过信标时序补偿同步触发多跳网络,实现数据传输前的同步调度,在达到最大化节点有效传输时间后,采用迸发传输机制实现多跳隐蔽信道数据的同步传输。经实验验证:该方法构建的隐蔽信道三跳误差低于0.4 s,单信道传输速率低于45 kbps,多信道传输速率高于65 kbps,数据传输最高吞吐量为150 bit/s,最高延迟为25 s,可减轻移动平台终端的传输压力。

In order to improve the data transmission throughput of mobile platform terminal and reduce the average delay of transmission,a data transmission synchronization method of covert channel of mobile platform terminal was proposed to adjust the private data to artificial noise,introduce the artificial noise into the normal signal to realize transmission,and complete the covert channel design of the mobile platform terminal.The clock synchronous scheduling method was used to optimize the transmission of single covert channel,and the multi hop network was triggered synchronously through beacon timing compensation to realize the synchronous scheduling before data transmission.After maximizing the effective transmission time of nodes,the burst transmission mechanism was used to realize the synchronous transmission of multi hop covert channel data.The experimental results show that the three-hop error of the covert channel constructed by this method is less than 0.4s,the single channel transmission rate is less than 45kbps,the multi-channel transmission rate is higher than 65kbps,the maximum throughput of data transmission is 150bit/s,and the maximum delay is 25s,which can reduce the transmission pressure of mobile platform terminals.
