Queer cryptograms, anarchist cyphers: decoding Dennis Cooper's The marbled swarm: a novel [PDF]
, 2012 Concentrating on Dennis Cooper’s latest work, The Marbled Swarm: A Novel, a fiendishly complex, experimental tale of murder and cannibalism in Cooper’s adopted home city of Paris, I show that both the subject of the text and its formal architecture are ...

Covert Communication over Adversarially Jammed Channels [PDF]
2018 IEEE Information Theory Workshop (ITW), 2018 Suppose that a transmitter Alice potentially wishes to communicate with a receiver Bob over an adversarially jammed binary channel. An active adversary James eavesdrops on their communication over a binary symmetric channel (BSC(q)), and may maliciously flip (up to) a certain fraction p of their transmitted bits based on his observations. We consider a

, 2014 Encryption prevents unauthorized decoding, but does not ensure stealth---a security demand that a mere presence of a message be undetectable. We characterize the ultimate limit of covert communication that is secure against the most powerful physically-permissible adversary.

Covert communications on renewal packet channels [PDF]
2016 54th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2016 Security and privacy are major concerns in modern communication networks. In recent years, the information theory of covert communications, where the very presence of the communication is undetectable to a watchful and determined adversary, has been of great interest.

MRCC: A Practical Covert Channel Over Monero With Provable Security
IEEE Access, 2021 Covert channels are designed to protect the communication relationship of the sender and receiver. Traditional covert channels have become insecure due to the continuous improvement of traffic analysis techniques. In this context, there is an urgent need

, 2016 We consider covert communication using a queuing timing channel in the presence of a warden. The covert message is encoded using the inter-arrival times of the packets, and the legitimate receiver and the warden observe the inter-departure times of the ...

Communication in a Poisson Field of Interferers -- Part II: Channel Capacity and Interference Spectrum [PDF]
, 2007 In Part I of this paper, we presented a mathematical model for communication subject to both network interference and noise, where the interferers are scattered according to a spatial Poisson process, and are operating asynchronously in a wireless ...

A Covert Channel Over VoLTE via Adjusting Silence Periods
IEEE Access, 2018 Covert channels represent unforeseen communication methods that exploit authorized overt communication as the carrier medium for covert messages. Covert channels can be a secure and effective means of transmitting confidential information hidden in overt
