摘要：Abstract: This paper addresses security issues of a cyber-physical system (CPS) under denial-of-service (DoS) attacks. The measurements of a sensor are transmitted to a remote estimator over a vulnerable communication channel, which may be congested by an intelligent attacker. Aiming at improving the estimation accuracy under a limited energy budget, we propose a novel acknowledgement-based (ACK-based) cheating scheme for the sensor to confuse the attacker, from which we prove an optimal deception-based transmission schedule within the whole transmission/deception schedule sets. The schedule has a very simple structure. Numerical comparisons are provided to illustrate the developed results.
