Covert Communication in Mobile Applications (T) [PDF]

2015 30th IEEE/ACM International Conference on Automated Software Engineering (ASE), 2015
This paper studies communication patterns in mobile applications. Our analysis shows that 63% of the external communication made by top-popular free Android applications from Google Play has no effect on the user-observable application functionality. To detect such covert communication in an efficient manner, we propose a highly precise and scalable ...

Covert communication method based on tripartite generative adversarial network [PDF]

Tongxin xuebao, 2023
A novel tripartite generative adversarial network (TripartiteGAN) and a covert communication method based on TripartiteGAN were designed for jointly optimizing the transmission covertness and the demodulation accuracy of the covert message.The ...

Research on multi-address time-based blockchain covert communication method [PDF]

Tongxin xuebao, 2023
Aiming at the problem of low amount of information carried by the existing block timestamp interval hiding method, a multi-address time-based blockchain covert communication method was proposed.Firstly, the ciphertext was split and transmitted by ...

Covert Communication in Autoencoder Wireless Systems

CoRR, 2023
Hiding the wireless communication by transmitter Alice to intended receiver Bob from a capable and attentive adversary Willie has been widely studied under the moniker "covert communications". However, when such covert communication is done in the presence of allowable system communications, there has been little study of both hiding the signal and ...

Exploiting Temporal Variability in TCP Timestamps for Covert Channel Design

IEEE Access
Information is a valuable asset for individuals, organizations, and governments, making secure transmission a critical concern. Cryptographic techniques are widely used to protect communication; however, in scenarios where the mere detection of ...

FAS for Secure and Covert Communications

IEEE Internet of Things Journal
This letter considers a fluid antenna system (FAS)-aided secure and covert communication system, where the transmitter adjusts multiple fluid antennas' positions to achieve secure and covert transmission under the threat of an eavesdropper and the detection of a warden.

Geolocation of covert communication entity on the Internet for post-steganalysis

EURASIP Journal on Image and Video Processing, 2020
Geolocation of covert communication entity is significantly important for the forensics of the crime but has significant challenges when the steganalyst locks the guilty actor IP and wants to know the physical location of the actor.

Achievability of Covert Quantum Communication

2025 IEEE International Symposium on Information Theory (ISIT)
We explore covert communication of qubits over an arbitrary quantum channel. Covert communication conceals the transmissions in the channel noise, ensuring that an adversary is unable to detect their presence. We show the achievability of a $\textit{square root law}$ (SRL) for quantum covert communication similar to that for classical: $M(n)\propto ...
