Free-space optical channel estimation for physical layer security
Hiroyuki Endo, Mikio Fujiwara, Mitsuo Kitamura +10
We present experimental data on message transmission in a free-space optical (FSO) link at an eye-safe wavelength, using a testbed consisting of one sender and two receiver termina…
Achievable Secrecy Rates of an Energy Harvesting Device
Alessandro Biason, Nicola Laurenti, Michele Zorzi
The secrecy rate represents the amount of information per unit time that can be securely sent on a communication link. In this work, we investigate the achievable secrecy rates in…
Achievable Secrecy Rates over MIMOME Gaussian Channels with GMM Signals in Low-Noise Regime
Francesco Renna, Nicola Laurenti, Stefano Tomasin
We consider a wiretap multiple-input multiple-output multiple-eavesdropper (MIMOME) channel, where agent Alice aims at transmitting a secret message to agent Bob, while leaking no…
Parallel BCC with One Common and Two Confidential Messages and Imperfect CSIT
Ahmed Benfarah, Stefano Tomasin, Nicola Laurenti
We consider a broadcast communication system over parallel sub-channels where the transmitter sends three messages: a common message to two users, and two confidential messages to…
Secrecy Transmission on Block Fading Channels: Theoretical Limits and Performance of Practical Codes
Marco Baldi, Marco Bianchi, Franco Chiaraluce +3
We consider a system where an agent (Alice) aims at transmitting a message to a second agent (Bob) over a set of parallel channels, while keeping it secret from a third agent (Eve)…
On the Achievable Error Region of Physical Layer Authentication Techniques over Rayleigh Fading Channels
Augusto Ferrante, Nicola Laurenti, Chiara Masiero +2
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…
Low-power Secret-key Agreement over OFDM
Francesco Renna, Nicola Laurenti, Stefano Tomasin +5
Information-theoretic secret-key agreement is perhaps the most practically feasible mechanism that provides unconditional security at the physical layer to date. In this paper, we…
Exact Spectral Analysis of Single-h and Multi-h CPM Signals through PAM decomposition and Matrix Series Evaluation
G. Cariolaro, T. Erseghe, N. Laurenti
In this paper we address the problem of closed-form spectral evaluation of CPM. We show that the multi-h CPM signal can be conveniently generated by a PTI SM. The output is governe…
