Physical Layer Security in a SISO Communication using Frequency-Domain Time-Reversal OFDM Precoding and Artificial Noise Injection
Sidney Jonathan Golstein, François Rottenberg, François Horlin +2
A frequency domain (FD) time-reversal (TR) precoder is proposed to perform physical layer security (PLS) in single-input single-output (SISO) systems using orthogonal frequency-div…
Monitoring Large Crowds With WiFi: A Privacy-Preserving Approach
Jean-François Determe, Sophia Azzagnuni, Utkarsh Singh +2
This paper presents a crowd monitoring system based on the passive detection of probe requests. The system meets strict privacy requirements and is suited to monitoring events or b…
MAC Address Anonymization for Crowd Counting
Jean-François Determe, Sophia Azzagnuni, François Horlin +1
Research has shown that counting WiFi packets called probe requests (PRs) implicitly provides a proxy for the number of people in an area. In this paper, we discuss a crowd countin…
Impact of Realistic Propagation Conditions on Reciprocity-Based Secret-Key Capacity
François Rottenberg, Philippe De Doncker, François Horlin +1
Secret-key generation exploiting the channel reciprocity between two legitimate parties is an interesting alternative solution to cryptographic primitives for key distribution in w…
