Concurrent Covert Communication Channels
2010This paper introduces a new steganographic technique in which a set of concurrent hidden channels are established between a sender and multiple receivers. Each channel is protected by a separate key. The method can work with JPEG blocks in which an 8 × 8 block is divided into four non-overlapping sets, each consisting a covert channel that hides a ...

Quantifying and Classifying Covert Communications on Android
Mobile Networks and Applications, 2013By exploiting known covert channels, Android applications today are able to bypass the built-in permission system and share data in a potentially untraceable manner. These channels have sufficient bandwidth to transmit sensitive information, such as GPS locations, in real-time to collaborating applications with Internet access. In this paper, we extend

Covert computer and network communications
Proceedings of the 4th annual conference on Information security curriculum development, 2007The ex-filtration of confidential information across communication networks is a challenging problem. It is possible for transmissions to be hidden or masked in such a way to circumvent the security policies of an organization. An objective might be to make contacts "invisible" to all parties except designates.

Covert Communication for DTD Documents Slicing
2010 International Conference on E-Business and E-Government, 2010In this work, a novel covert communication method for DTD documents is introduced. The relationship is found between an arbitrary 0,1 string and DTD documents. According to some slicing criterion, a secret communication is completed. Furthermore, a covert communication model is also proposed and an algorithm is discussed in detail.

Covert Communications in a Dynamic Interference Environment
2018 IEEE 19th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2018Much of security research focuses on preventing an adversary from deciphering a message's content, but there are a number of applications that motivate the more challenging goal of “covert” communications: transmitter Alice conveying information to legitimate receiver Bob while preventing a capable and attentive adversary Willie from detecting the ...

On covert communication in advertising
Journal of Pragmatics, 2004Abstract This paper investigates the notion of covert communication in advertisements. I begin by discussing the role of intentions in communication, outlining the relevance-theoretic view. Taking the work of Keiko Tanaka (1994/1999. Advertising Language: A Pragmatic Approach to Advertisements in Britain and Japan.
