Secrecy Rate Analysis in The Cooperative Communication System
2021 IEEE International Conference on Consumer Electronics-Taiwan (ICCE-TW), 2021With the assistance of relays, cooperative communication provides the benefits of spatial diversity to improves the system performance. It could be prospective for the application of wireless networks. The issue of security is highly requested for personal privacy in the internet.

Ergodic Secrecy Rates of Secure Wireless Communications
2014 IEEE Military Communications Conference, 2014Two unified analytical frameworks that facilitate the evaluation of the ergodic secrecy rates of Wyner wiretap channel in generalized fading environments without/with diversity receivers are developed. In contrast to prior work that is limited to only the Rayleigh fading environment, our new formulas expressed in terms of only the moment generating ...

MIMO multi-user secrecy rate analysis
2014 IEEE International Conference on Communications (ICC), 2014In this paper, we consider the broadcast channel with confidential messages and eavesdroppers (BCCE), where a multi-antenna base station simultaneously communicates to multiple potentially malicious users, in the presence of external eavesdroppers randomly located according to a Poisson point process (PPP).

Secrecy Rate Pair Constraints for Secure Throughput
2014 IEEE Military Communications Conference, 2014Physical layer security, which is an alternative to traditional cryptographic methods, has emerged as a promising candidate to protect wireless transmissions from an eavesdropper. An important measure of physical layer security is the secrecy outage: the event when the instantaneous secrecy capacity, which for the considered scenario is the difference ...

On Ergodic Secrecy Rate for Gaussian MISO Wiretap Channels
IEEE Transactions on Wireless Communications, 2011A Gaussian multiple-input single-output (MISO) wiretap channel model is considered, where there exists a transmitter equipped with multiple antennas, a legitimate receiver and an eavesdropper, each equipped with a single antenna. We study the problem of finding the optimal input covariance that maximizes the ergodic secrecy rate subject to a power ...

Going beyond Secrecy Rate via Information Jamming
2018 IEEE Global Communications Conference (GLOBECOM), 2018Cooperative jamming approach has been commonly used in the field of physical layer security to achieve a good secrecy rate of wireless networks. In this approach, the Gaussian noise signal sent by a friendly jammer can disrupt the reception of the eavesdropper, however, it may also interfere with the legitimate receiver.

Efficient Algorithm for Selecting Secrecy Rate Maximizing Antennas
IEEE Communications Letters, 2013Antenna selection (AS) is poised to provide solutions to hardware complexity issues while guaranteeing untappable information flow. We investigate the AS problem set up in the context of linear precoder design for secrecy rate maximization of a multiple-input single-output system. The original problem is both non-tractable and nonconvex.
