Query: Compromised ACC vehicles can degrade current mixed-autonomy traffic
  performance while remaining stealthy against detection   We demonstrate that a supply-chain level compromise of the adaptive cruise
control (ACC) capability on equipped vehicles can be used to significantly
degrade system level performance of current day mixed-autonomy freeway
networks. Via a simple threat model which causes random deceleration attacks
(RDAs), compromised vehicles create congestion waves in the traffic that
decrease average speed and network throughput. We use a detailed and realistic
traffic simulation environment to quantify the impacts of the attack on a model
of a real high-volume freeway in the United States. We find that the effect of
the attack depends both on the level of underlying traffic congestion, and what
percentage of ACC vehicles can be compromised. In moderate congestion regimes
the attack can degrade mean commuter speed by over 7%. In high density regimes
overall network throughput can be reduced by up to 3%. And, in moderate to high
congestion regimes, it can cost commuters on the network over 300 USD/km hr.
All of these results motivate that the proposed attack is able to significantly
degrade performance of the traffic network.
  We also develop an anomaly detection technique that uses GPS traces on
vehicles to identify malicious/compromised vehicles. We employ this technique
on data from the simulation experiments and find that it is unable to identify
compromised ACCs compared to benign/normal drivers. That is, these attacks are
stealthy to detection. Stronger attacks can be accurately labeled as malicious,
motivating that there is a limit to how impactful attacks can be before they
are no longer stealthy.
  Finally, we experimentally execute the attack on a real and commercially
available ACC vehicle, demonstrating the possible real world feasibility of an
RDA.
