In this paper, we study using Destination Artificial Noise (DAN) besides Source Artificial
Noise (SAN) to enhance physical layer secrecy with an outage probability based approach …

The inherent broadcast characteristics of wireless medium make wireless data transmission
difficult to be shielded from unintended recipients. As such, secure communication over …

In this letter, we investigate the performance of the secrecy capacity in an amplify-and-
forward dual-hop network for both distributed beamforming (DBF) and opportunistic relaying …

Due to the nature of a wireless medium, a wireless channel is susceptible to malicious
nodes, which encourages the consideration of secrecy in many applications such as satellite …

In a wireless network, it is necessary to make the security of the network so high that
eavesdroppers cannot intercept the messages. If a key message is divided into several …

The optimal scaling law of secrecy capacity as well as the corresponding achievable
scheme have not been fully investigated in ad hoc networks. In this paper, we consider an …

In wireless communication, coalitional game theory has been a promising approach for
analyzing cooperative networks to improve the physical layer security. In this paper, we …

Recently, cybercriminal activities in wireless communications systems are growing due to
the fact that more and more emerging malware programs (also known as computer viruses) …

For communication secrecy, we develop the cooperative transmission strategies by taking
into account the degree of trust between users as well as physical wireless channels. For a …

The study of secrecy capacity of wireless networks, considering variety of powerful attacks is
currently of great interest. In this paper, we have considered a possible attack scenario …
