| 摘 要： | 目前针对隐蔽信道的研究工作大部分都基于互联网协议，在数字电视中实现隐蔽通信是信息隐藏技术的一个新方向。论文在隐蔽信道信息传递框架的基础上，阐明了数字电视网络中隐蔽信道存在的可能性和必然性。本文提出了基于TS包的填充域与PCR域保留位的信息隐藏方法，并实现仿真，然后对两种隐藏方案的性能进行了分析与比较。研究工作对在数字电视网络中构建隐蔽信道有一定的指导意义。

| Abstract: | The existing covert channels typically focus on Internet Protocol Stack. Constructing covert channels based on Digital Television Network has not been studied before. Firstly, this thesis demonstrate the possibility and inevitability of the covert channels in DVB Network on the foundation of the information transmission framework. Then, two kinds of covert channels based on the padding filed of the TS packet and the reserved bits of PCR are proposed and simulated respectively. At last, their performances are evaluated and compared. The research is helpful on constructing covert channels based on Digital Television Network. |
