This complete guide to physical-layer security presents the theoretical foundations, practical
implementation, challenges and benefits of a groundbreaking new model for secure …

We consider the problem of secure communications over the two-way wiretap channel
under a strong secrecy criterion. We improve existing results by developing an achievable …

Secure communication with feedback is studied. An achievability scheme in which the
backward channel is used to generate a shared secret key is proposed. The scenario of …

Most practical communication links are bidirectional. In these models, since the source node
also receives signals, its encoder has the option of computing its output based on the …

For bi-directional communication, the most general form of encoders should consider the
signals received in the past as inputs. However, in practice, it would also be highly desirable …

This dissertation studies the fundamental rate limits of wireless communication systems
through which confidential messages can be transmitted without being intercepted by an …

In this paper, we propose a feedback scheme for transmitting secret messages between two
legitimate parties, over an eavesdropped communication link. Relative to Wyner's traditional …

Physical layer security (PLS), which is based on information-theoretic principles of message
confidentiality, has attracted considerable attention in recent years. This paper provides a …
