摘要： 针对传统车联网协议下的隐蔽信道构建方式单一、无法适用于复杂网络环境的问题,通过分析轻量级物联网应用层协议Websocket的数据帧格式和通信机制,提出了一种基于Websocket协议的车联网隐蔽信道构建方法。该方法利用信息分离聚合算法将待发送的隐蔽信息进行多维传输,以提升隐蔽信道的传输速率和抗暴露性。同时,考虑到车联网网络的动态拓扑特性,基于跳频技术自适应变换信息分离聚合方式和编码映射表。为了提高信道的隐蔽性,通过最小二乘算法模拟了正常网络流量的传输特性。仿真实验结果表明,所构建的隐蔽信道在面对较差的网络环境时,受到的网络波动影响较小,具有较好的鲁棒性;并且相较于单一维度传输的隐蔽信道,在隐蔽性和传输速率方面有一定的提升。

Abstract: Aiming at the problem that the construction method of covert channel under traditional Internet of Vehicles protocol is single and cannot be applied to complex network environment,a construction method of covert channel in Internet of Vehicles based on WebSocket protocol is proposed by analyzing the data frame format and communication mechanism of Websocket－a lightweight application layer protocol of Internet of Things.This method uses information separation and aggregation algorithm to transmit the covert information in multiple dimensions to enhance the transmission rate and anti-exposure of the covert channel.Besides,considering the dynamic topological characteristics of the Internet of Vehicles network,the information separation and aggregation mode and coding mapping table are transformed adaptively based on frequency hopping technology.Finally,in order to improve the concealment of the channel,the least square algorithm is used to simulate the transmission characteristics of normal network traffic.The results of simulation experiments show that the constructed covert channel is less affected by network fluctuations and has better robustness when facing poor network environment.And compared with the covert channel with single-dimension transmission,it has certain improvement in terms of concealment and transmission rate.
