Covert Channels in Internet Protocols: A Survey
David Llamas, Colin Allison, Alan Miller · 2005
The creation of covert channels in public computer networks can prove an effective means of information hiding and secret communication. With the widespread adoption of the Internet the TCP/IP suite of protocols have become pervasive, and therefore an attractive target for covert channel exploitation. This paper gives a brief overview of covert channels in communication networks, and presents a brief survey of some recent and relevant papers on the use of covert channels in the common Internet protocols.
