【摘要】：为了提高隐秘信息的安全性,提出了一种具有不可恢复性的网络时间隐蔽信道。将实时获取的网络特征往返时延(RTT)的值嵌入包间间隔中,使隐蔽信道的时间特征随着网络状况实时变化,并在发送方和接收方采用前向纠错编码(Tornado)对隐蔽信道进行前向纠错。实验分别搭建了现有隐蔽信道与新型隐蔽信道的发生器,根据不同网络状况,对传输速率和传输正确率进行对比实验。实验结果显示,在保证较高的解码正确率的同时,新型隐蔽信道的传输速率随着网络状况的不同而变化,对网络情况有一定的适应性,并且通过将实时网络特征编码到新型隐蔽信道中,提升了隐蔽信道整体的数据安全性和不可恢复性。
[Abstract]:In order to improve the security of secret information, a non-recoverable network-time covert channel is proposed, in which the RTT values of the network features obtained in real time are embedded in the inter-packet interval. The time characteristics of the covert channel are changed in real time with the network condition. The forward error correction of the covert channel is carried out by using forward error correction code (Tornado) on the sender and receiver. The existing covert channel and the new covert channel generator are constructed respectively. According to different network conditions, the transmission rate and transmission accuracy are compared. The experimental results show that the high decoding accuracy is guaranteed at the same time. The transmission rate of the new covert channel varies with the network conditions, and it has some adaptability to the network situation, and encodes the real-time network features into the new covert channel. Improves the data security and non-recoverability of the covert channel as a whole.
