Study of IP covert timing channel''s communication protocol
IP时间隐通道通信协议的研究

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.
