Covert computer and network communications

Proceedings of the 4th annual conference on Information security curriculum development, 2007
The 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, 2010
In 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), 2018
Much 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 ...
