The Tree of Light as interstellar optical transmitter system
Elisa Bazzani, Anna Valeria Guglielmi, Roberto Corvaja +8
This work aims at investigating the optical transmission system needed for such lightweight sail, taking into account the physical constraints of such unprecedented link and focusi…
It Is Rude to Ask a Sensor Its Age-of-Information: Status Updates Against an Eavesdropping Node
Laura Crosara, Nicola Laurenti, Leonardo Badia
We consider periodical status updates between a transmitter and a legitimate receiver, in the presence of an eavesdropper that is sometimes able to capture pieces of information. W…
On the Optimal Spoofing Attack and Countermeasure in Satellite Navigation Systems
Laura Crosara, Francesco Ardizzon, Stefano Tomasin +1
The threat of signal spoofing attacks against GNSS has grown in recent years and has motivated the study of anti-spoofing techniques. However, defense methods have been designed on…
Information Theoretic Key Agreement Protocol based on ECG signals
Anna V. Guglielmi, Alberto Muraro, Giulia Cisotto +1
Wireless body area networks (WBANs) are becoming increasingly popular as they allow individuals to continuously monitor their vitals and physiological parameters remotely from the…
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…
Experimental quantum key distribution with finite-key security analysis for noisy channels
Davide Bacco, Matteo Canale, Nicola Laurenti +2
In quantum key distribution implementations, each session is typically chosen long enough so that the secret key rate approaches its asymptotic limit. However, this choice may be c…
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…
Adaptive Real Time Selection for Quantum Key Distribution in Lossy and Turbulent Free-Space Channels
Giuseppe Vallone, Davide Marangon, Matteo Canale +7
Quantum Key Distribution (QKD) allows to share random keys between two users with unconditional security: the key is usually generated by exchanging a stream of photons. The long-t…
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…
Secret Message Transmission by HARQ with Multiple Encoding
Stefano Tomasin, Nicola Laurenti
Secure transmission between two agents, Alice and Bob, over block fading channels can be achieved similarly to conventional hybrid automatic repeat request (HARQ) by letting Alice…
Adaptive Discrimination Scheme for Quantum Pulse Position Modulation Signals
Nicola Dalla Pozza, Nicola Laurenti
In the communication scenario, we consider the problem of the discrimination between the signals of the Quantum Pulse Position Modulation. We propose a receiver scheme that employs…
Optimal Binary Codes and Measurements for Classical Communication over Qubit Channels
Nicola Dalla Pozza, Nicola Laurenti, Francesco Ticozzi
We propose constructive approaches for the optimization of binary classical communication over a general noisy qubit quantum channel, for both the error probability and the classic…
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…
