Feature Topic, Vol. 21, No. 9, 2024--Intelligent Covert Communication

Intelligent Covert Communication


As an ever-increasing amount of private and confidential information will be delivered over current and future wireless networks, the openness and broadcast natures of the ubiquitous wireless medium are bring concerns and security risks to our society. Specifically, in some certain scenarios that require a high level of security and privacy, such as health care or finial activities, the initial exposure of transmitted information can lead to unpredictable threats and losses. Consequently, covert communication, also known as low probability of detection (LPD) communication, has recently attracted increasing attentions in academic and industry, due to its special advantage of hiding the wireless transmission behaviors. Based on some preliminary research results using information theory, covert communication has been proven to be able to achieve information transmission covertly, i.e., subject to a negligible probability of being detected by a warden. This leads to various covert transmission strategies with established confidence limits. Unlike traditional upper-layer encryption techniques, covert communications are not conditioned on the limited information processing and computing capabilities of the eavesdropper/warden. Covert communication is able to protect the fundamental and extensive range of legitimate communications.

 

In the development of fundamental theories on covert communications, the square root law established the theoretical bounds on covert transmission, which revealed the limit on the covert transmission rate. Following this result, diverse approaches have been developed to effectively facilitate covert communication by exploiting uncertainties in noise, channel, interference power and the timing of information transmission. Apart from the above, researchers are introducing other assisted schemes using relays, cooperative jammers, full-duplex receivers, and intelligent reflective surfaces (IRS) to enhance covert communication performance. However, there are still challenging issues in practical applications of the existing covert transmission methods and strategies. Current studies generally consider the optimal detection performance from the perspective of the eavesdropper/warden, but in fact, due to unknown factors, such as the uncertainty on the eavesdropper/warden's location, the unavailability of channel state information (CSI), and the requirement of real-time detection, the true covert communication performance is not available to the legitimate users or system designers, which leads to that covert communication may still not be achievable in practical scenarios and its performance cannot be measured completely and accurately.

 

Therefore, intelligent covert communication, i.e., the use of intelligent methods to achieve covert communication, becomes a promising direction for achieving communication covertness in practical applications. For example, owning to the signi?cant advances in machine learning (ML), the determination of CSI from a wireless link’s surrounding environment becomes feasible. In particular, the mapping function can be well mimicked by some model ?tting adopted in ML. These models can be trained accurately with a large amount of real data samples to extract useful environmental information. In certain covert communication scenarios, ML methods can be applied to the covert transmitter/collaborator side, for the sake of estimating channel information without explicit feedback/detection, which helps to achieve signal intensification or cancellation, and thus enables a more practical scheme for achieving covert transmission.

 

The main goal of this special issue is to attract academic and industrial researchers in an effort to identify and discuss the major technical challenges, recent breakthroughs, and new applications related to intelligent covert communications.
