ABSTRACT
We describe the design, implementation and evaluation of a reliable and secure protocol to establish a covert channel that not only maintains a high degree of stealthiness, but also provides reliability despite temporary data loss as well as data confidentiality. An important feature of our proposed protocol is that it can be embedded in any legitimate channel that is based on IP. In this paper, we describe our protocol using ICMP. In particular, the proposed protocol satisfies four important properties: stealthiness, lightweight, confidentiality and integrity, and reliability.

IP Covert Channel Detection
A covert channel can occur when an attacker finds and exploits a shared resource that is not designed to be a communication mechanism. A network covert channel operates by altering the timing of otherwise legitimate network traffic so that the arrival ...
A Protocol for Building Secure and Reliable Covert Channel
PST '08: Proceedings of the 2008 Sixth Annual Conference on Privacy, Security and TrustThis paper presents a secure and lightweight protocol for reliable data transfer through moderate bandwidth covert channels. Though data transfer through covert channels is not unprecedented, existing covert channels have been restricted to covert ...
Covert Communication With Channel-State Information at the Transmitter
We consider the problem of covert communication over a state-dependent channel, where the transmitter has causal or noncausal knowledge of the channel states. Here, covert means that a warden on the channel should observe similar statistics when the ...
