针对现有IP时间隐通道通信工具之间因缺乏统一的协议约束而不能互联互通的问题,在OSI参考模型的基础上建立IP时间隐通道四层协议模型,分析了协议各分层的功能,给出了具体的设计方案,并实现了一个满足分层协议功能要求的IP时间隐通道实用通信软件。
To solve the problem that the existing IP covert timing channel tools can not communicate with each other due to the lack of uniform protocol constraint,based on the OSI/RM,this paper established four layer protocol model of IP covert timing channel and gave the specific design.Furthermore,implemented a practical IP covert timing channel software which meeting the requirements of the hierarchical communication protocol.
