Optimizing DoS attack energy with imperfect acknowledgments and energy harvesting constraints in cyber-physical systems

作者:

Highlights:

• A novel attack model based on unreliable feedback information is formulated, and the jammer is constrained by energy harvesting.

• To maximize the average estimation error covariance, we set up the Bellman optimal equations with finite and infinite time horizons respectively, and obtain the optimal DoS attack energy allocation strategy.

• Some structural properties are given about energy allocation. For fixed available energy, the optimal DoS attack energy allocation strategy is nondecreasing with the state of the remote estimator. A myopic strategy with simple structure and easy implementation is proposed.
