Query: Learning-based attacks in Cyber-Physical Systems: Exploration,
  Detection, and Control Cost trade-offs   We study the problem of learning-based attacks in linear systems, where the
communication channel between the controller and the plant can be hijacked by a
malicious attacker. We assume the attacker learns the dynamics of the system
from observations, then overrides the controller's actuation signal, while
mimicking legitimate operation by providing fictitious sensor readings to the
controller. On the other hand, the controller is on a lookout to detect the
presence of the attacker and tries to enhance the detection performance by
carefully crafting its control signals. We study the trade-offs between the
information acquired by the attacker from observations, the detection
capabilities of the controller, and the control cost. Specifically, we provide
tight upper and lower bounds on the expected $\epsilon$-deception time, namely
the time required by the controller to make a decision regarding the presence
of an attacker with confidence at least $(1-\epsilon\log(1/\epsilon))$. We then
show a probabilistic lower bound on the time that must be spent by the attacker
learning the system, in order for the controller to have a given expected
$\epsilon$-deception time. We show that this bound is also order optimal, in
the sense that if the attacker satisfies it, then there exists a learning
algorithm with the given order expected deception time. Finally, we show a
lower bound on the expected energy expenditure required to guarantee detection
with confidence at least $1-\epsilon \log(1/\epsilon)$.
