This paper considers channel coding problems with the requirement of guaranteeing
information integrity in the presence of malicious relays (MRs). The proved random channel …

We consider a system where an agent (Alice) aims at transmitting a message to a second
agent (Bob) over a set of parallel channels, while keeping it secret from a third agent (Eve) …

In a typical secure communication system, messages undergo two different encodings: an
error-correcting code is applied at the physical layer to ensure correct reception by the …

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 …

This paper investigates the impact of cooperation with an untrusted relay in multi-source
multi-destination networks. The set up considered is one where the relay is the only means …

This paper presents a random coding scheme with which two nodes can exchange
information with guaranteed integrity over a two-way Byzantine relay. This coding scheme is …

We consider a system where an agent (Alice) aims at transmitting a message to a second
agent (Bob) over a set of parallel channels, while keeping it secret from a third agent (Eve) …

In applications of wireless packet-oriented data networks, a special coding scheme, the
hybrid automatic retransmission request (HARQ) exhibits high throughput efficiency by …

We establish upper and lower bounds on the secrecy capacity of the degraded Gaussian
diamond-wiretap channel, and identify several ranges of channel parameters where these …

In this study, the authors propose an equivocation scheme for wiretap channels, which is
composed of bit‐extension mapping, coset coding and hybrid automatic repeat request …
