Achievable Physical-Layer Security Over Composite Fading Channels

On the Achievable Error Region of Physical Layer Authentication Techniques over Rayleigh Fading Channels

For a physical layer message authentication procedure based on the comparison of channel estimates obtained from the received messages, we focus on an outer bound on the type I/II error probability region. Channel estimates are modelled as multivariate Gaussian vectors, and we assume that the attacker has only some side information on the channel estimate, which he does not know directly. We de...

Physical Layer Secrecy Performance Analysis over Rayleigh/Nakagami Fading Channels

1 Abstract—The broadcast nature of wireless communications makes it vulnerable to attack or eavesdropping. Therefore, information security is an important issue in wireless communications, especially in distributed networks such as wireless sensor networks and ad hoc wireless networks. In this paper, we present the physical layer secrecy performance analysis of singleinput single-output (SISO) ...

Energy Detection of Unknown Signals over Composite multipath/shadowing Fading Channels

In this paper, the performance analysis of an energy detector is exploited over composite multipath/shadowing fading channels, which is modeled by Rayleigh-lognormal (RL) distribution. Based on an approximate channel model which was recently proposed by the author, the RL envelope probability density function (pdf) is approximated by a finite sum of weighted Rayleigh pdfs. Relying on this inter...

On The Physical Layer Security Under κ-μ Shadowed Fading Channels With Diversity Approaches

This paper presents a investigation on the performance of security under κ-μ shadowed fading channels using the Wyner’s classic wiretap model. A better fit was presented for the κ-μ shadowed fading channel curves in relation to other fading models, as Rayleigh and Nakagami-m. Results and analyses are obtained through the Secrecy Outage Probability, the Strictly Positive Secrecy Capacity and Ave...
