Covert Messaging through TCP Timestamps
[chapter]
2003
Lecture Notes in Computer Science
We present a protocol for sending data over a common class of low-bandwidth covert channels. Covert channels exist in most communications systems and allow individuals to communicate truly undetectably. However, covert channels are seldom used due to their complexity. Our protocol is both practical and secure against attack by powerful adversaries. We implement our protocol on a standard platform (Linux) exploiting a channel in a common communications system (TCP timestamps).
