In this paper, a novel message authentication model using the same key over wiretap
channel is proposed to achieve information-theoretic security. Specifically, in the proposed …

We consider the two-user multiple-input multipleoutput (MIMO) interference channel with
confidential messages (ICCM). We determine the exact secure degrees of freedom (sdof) …

The downlink of symmetric Cloud Radio Access Networks (C-RANs) with multiple relays and
a single receiver is studied. Lower and upper bounds are derived on the capacity. The lower …

We study deterministic approximations of the Gaussian two-user multiple access wiretap
channel (G-MAC-WT) and the Gaussian wiretap channel with a helper (G-WT-H). These …

In this paper, we study outer bounds on the capacity region of the downlink multicell
processing model with finite backhaul capacity for the simple case of two base stations and …

In this paper, we study a diamond-relay channel where the source is connected to M relays
through orthogonal links and the relays transmit to the destination over a wireless multiple …

Wireless communications are highly susceptible to eavesdropping due to their inherent
broadcast nature. Recent works have proposed the use of interference for impeding the …

In this letter, we consider the Gaussian diamond-wiretap channel with conferencing links
between relays for the following three cases: 1) both conferencing links are confidential; 2) …

In this letter, we establish the secure degrees-of-freedom of the Gaussian diamond-wiretap
channel with rate-limited relay cooperation, where the eavesdropper not only observes the …

We investigate the secure degrees of freedom (SDoF) for the two-way 2× 2× 2 MIMO
interference channel (IC) under three wiretap models, ie, the confidential messages (CM) …
