摘要
针对传统网络隐蔽信道无法适用于低功耗受限制设备的不足,通过研究轻量级物联网应用协议CoAP,提出并实现一种基于CoAP协议参数序列的隐蔽信道构建方法。该方法不需要修改协议数据单元和控制双方同步,克服了已有物联网隐蔽信道的固有弊端。为了对抗重排序攻击,增添了完整性校验功能。性能分析表明该隐蔽信道具有良好的隐蔽性、鲁棒性和传输效率。
In view of the deficiency of traditional network hidden channel that is not suitable for low-power limited devices,a lightweight Internet of things application protocol CoAP is studied,and a hidden channel construction method based on CoAP protocol parameter sequence is proposed and implemented.This method did not need to modify the protocol data unit and control the synchronization of both parties,and overcame the inherent disadvantages of the existing hidden channels of the Internet of things.In order to resist the resort attack,integrity check function was added.Performance analysis shows that the hidden channel has good concealment,robustness and transmission efficiency.
