title = "Covert messaging through TCP timestamps",
abstract = "Covert channels exist in most communications systems and allow individuals to communicate truly undectably. However, covert channels are seldom used due to their complexity. A protocol for sending data over a common class of low-bandwidth covert channels has been developed. The protocol is secure against attack by powerful adversaries. The design of a practical system implementing the protocol on a standard platform (Linux) exploiting a channel in a common communications system (TCP timestamps) is presented. A partial implementation of this system has been accomplished.",
