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 ...

Secrecy Rate Analysis Against Aerial Eavesdropper
IEEE Transactions on Communications, 2019This paper studies the threat that an aerial eavesdropper can pose to terrestrial wireless communications, from an information-theoretic point of view. The achievable ergodic and the average $\epsilon $ -outage secrecy rates with no channel state information at the transmitter (i.e., with no CSIT) are analyzed for a transmitter–receiver pair on ...

The Meta Distributions of Secrecy Rate for the Downlink NOMA Systems
IEEE Wireless Communications Letters, 2021In this letter, the Meta distributions (MDs) of the secrecy rate in downlink non-orthogonal multiple access (NOMA) systems with randomly located eavesdroppers are investigated. Due to the complexity of calculation, the MDs for NOMA users are approximated by Beta approximation and the analytical expressions for the first two moments of conditional ...

Secrecy rate with friendly full-duplex relay
2015 IEEE Wireless Communications and Networking Conference (WCNC), 2015This paper considers the use of a friendly full-duplex (FD) relay to increase the secrecy rate over a fading channel between the legitimate source and destination in the presence of a naive or informed eavesdropper. Naive eavesdropper can only decode the received signals either from the source or from the relay, while informed eavesdropper can overhear

The achievable secrecy rate of MISO wiretap channels
2011 International Conference on Wireless Communications and Signal Processing (WCSP), 2011In this paper, we study the achievable secrecy rate of the multiple input single output (MISO) wiretap channel, which consists of a transmitter, a legitimate receiver and multiple eavesdroppers. The transmitter is equipped with multiple antennas, while the receiver and all the eavesdroppers each have a single antenna. We assume that the transmitter has

On the target secrecy rate for SISOME wiretap channels
2014 IEEE International Conference on Communications (ICC), 2014We propose a new framework for optimizing the target secrecy rate for SISOME wiretap channels when the instantaneous capacity of the eavesdropper's channel is not available at the transmitter. In our framework we introduce the effective secrecy throughput, a new optimization metric that implicitly captures the two key features of wiretap channels ...

Secrecy Rates for Relay Selection in OFDMA Networks
2011 Third International Conference on Communications and Mobile Computing, 2011In this paper, we study the secrecy communication using physical layer security in OFDMA networks. The expressions of secrecy rates and outage probability are derived in OFDMA networks using Decode-and-Forward (DF) strategy. Monte Carlo simulations are carried out to validate our analysis.
