On Known-Plaintext Attacks to a Compressed Sensing-based Encryption: A Quantitative Analysis
Valerio Cambareri, Mauro Mangia, Fabio Pareschi +2
Despite the linearity of its encoding, compressed sensing may be used to provide a limited form of data protection when random encoding matrices are used to produce sets of low-dim…
From Chirps to Random-FM Excitations in Pulse Compression Ultrasound Systems
Sergio Callegari, Marco Ricci, Salvatore Caporale +6
Pulse compression is often practiced in ultrasound Non Destructive Testing (NDT) systems using chirps. However, chirps are inadequate for setups where multiple probes need to opera…
Sample and Hold Errors in the Implementation of Chaotic Maps
Sergio Callegari, Riccardo Rovatti
Though considerable effort has recently been devoted to hardware realization of chaotic maps, the analysis generally neglects the influence of implementation inaccuracies. Here we…
Low-complexity Multiclass Encryption by Compressed Sensing
Valerio Cambareri, Mauro Mangia, Fabio Pareschi +2
The idea that compressed sensing may be used to encrypt information from unauthorised receivers has already been envisioned, but never explored in depth since its security may seem…
