EC4730 Covert Communications

Electronic signal and data communication mechanisms in which the presence of a message being transmitted is concealed in plain sight of other signals or data are presented. Information hiding in user data, protocol data, and radio, electronic, acoustic and other sensory signals is examined. The techniques of steganography, covert channels, low probability exploitation, and information concealment in analog signals are studied. Techniques and mechanisms for establishing robust, secure covert communication schemes are introduced. The detection, analysis, and abortion of adverse covert communication schemes are discussed. Design of systems suitable for attack and defense of covert communications using programmable logic devices is introduced. Low probability of detect, low probability of intercept, and anti-jamming techniques are reviewed. Embedding and extraction algorithms of steganography are presented. Related topics of watermarking and embedded malware are reviewed.
