Physical layer security (PLS) is promising for secure short-packet transmissions in ultra-
reliable and low-latency communications. The bottlenecks of applying PLS in practice …

Physical layer security (PLS) is emerging as an attractive security paradigm to complement
or even replace complex cryptography. Although information-theoretical transmission …

This letter studies the practical design of secure transmissions without knowing the
eavesdropper's channel state information (ECSI). An ECSI-irrelevant metric is introduced to …

We design a novel artificial-noise-aided secure ON-OFF transmission scheme in a wiretap
channel. We consider a practical scenario, where the multi-antenna transmitter only obtains …

In this paper, we investigate a large intelligent surface-enhanced (LIS-enhanced) system,
where a LIS is deployed to assist secure transmission. Our design aims to maximize the …

Physical layer security has recently been regarded as an emerging technique to
complement and improve the communication security in future wireless networks. The …

We consider the problem of secure communication with multiantenna transmission in fading
channels. The transmitter simultaneously transmits an information-bearing signal to the …

In this paper, we consider user scheduling and power allocation techniques for downlinks
where transmitted message must be kept confidential from all other unintended users and …

Secure communication with noisy feedback is studied in this correspondence. Unlike the
majority of previous research efforts where the eavesdropper's channel state information …

Physical layer security (PLS) has emerged as a new concept and powerful alternative that
can complement and may even replace encryption-based approaches, which entail many …
