Physical-layer device identification aims at identifying wireless devices during radio
communication by exploiting unique characteristics of their analog (radio) circuitry. This work …

We demonstrate relay attacks on Passive Keyless Entry and Start (PKES) systems used in
modern cars. We build two efficient and inexpensive attack realizations, wired and wireless …

Significant developments have taken place over the past few years in the area of vehicular
communication systems. Now, it is well understood in the community that security and …

Cyber‐physical systems (CPS) help create new services and applications by revolutionising
our world in different fields through their tight interactions and automated decisions. This is …

Despite the important role that WiFi networks play in home and enterprise networks they are
relatively weak from a security standpoint. With easily available directional antennas …

Attacker models are a fundamental part of research on security of any system. For different
application scenarios, suitable attacker models have to be chosen to allow comprehensive …

Cognitive radio network is designed to opportunistically exploit the licensed band. To deploy
a cognitive radio network, nodes need to perform the neighbor discovery process in order to …

In wormhole attacks, attackers create a low-latency link between two points in the network.
This can be achieved by either compromising two or more sensor nodes of the network or …

In this paper, we study channel-based authentication, where the receiver can identify and
authenticate the senders through channel vectors estimated from their frames. The …

Vehicular communications disclose rich information about the vehicles and their
whereabouts. Pseudonymous authentication secures communication while enhancing user …
