Title Design and implementation of TRCTC-based network covert channel

Abstract We are living in the information era，and with the rapid development of Internet, Internet information security has become a problem that people have to pay attention to。 Network-based covert channel has become an important research direction in the field of information security because of its hidden nature and the huge impact on network information security,so the research on the network covert channel has its reality and necessity。

The paper introduces firstly the basic concept and the communication model of covert channel,secondly explains the classification of covert channels and several covert channels with their advantages and disadvantages。Then compared with IPCTC,it introduces the relative algorithm of network covert channel based on TRCTC and explains its improvement，and based on the relative algorithm, the specific design and implementation are carried out on LINUX platform。Finally,a complete system is completed。The paper end up with the analysis and summary to the overall situation of the system,it reflects the function and benefits of the system, prospects for its future and provides the beneficial reference for related research。
