| 摘 要： | 介绍了常见的构建网络隐蔽通道技术。提出一种新的安全、可靠的网络隐蔽信息传输方法。采用ICMP数据包的选项部分作为隐蔽信息的载体,对该方法可以承载的信息容量进行了计算。与利用协议漏洞在数据包中直接嵌入机密信息构建隐蔽信道的方法相比,通过该方法建隐蔽信道能较好地解决机密信息传输过程中的丢失和失序问题,提高机密信息传输的可靠性。

| Abstract: | In the thesis,the conception of covert channels is introduced firstly,and then presented a secure and reliable method for data transfer.The method exploits ICMP packet as covert medium,and the information capacity was calculated by the method.Compared to comment cover channel using vulnerabilities of TCP/IP protocol definition or realization and directly embedding secret in the legislation channel.This method can rise the integrated and ability of the cover channel. |
