Quantum key distribution(QKD) technology provides proved unconditional security in pointto-point key transmissions based on quantum mechanics. However, several limitations, most prominently range,make it complex to construct large QKD network. The trusted relay QKD network is the most practical scene,and stochastic routing scheme was proposed to solve the fatal problem that some relay nodes may be controlled by adversary. But most results in stochastic routing scheme hinge on an adversary model without consideration of attacker's prior-knowledge and attack strategy. To reveal the security problem, we propose a new adversary model and apply it in grid-shaped partially-trusted relay QKD network. Then we analyze the best attack strategy and the impact on security under various situations *** and simulation results show that in some cases the security of stochastic routing scheme will be compromised, and a generalized upper bound for the overall safe probability is obtained. We also discuss how to alleviate the security problem, making the network more robust to attacks.

There has been a surge of interests in the security of cyber-physical systems(CPSs), yet it is commonly assumed that the adversary has a full knowledge of physical system models. This paper argues that such an unrealistic assumption can be relaxed: the adversary might still be able to identify the system model by passively observing the control input and sensory data. In such a setup, the attack with knowledge of input-output data can be categorized as a Known-Plaintext Attack. A necessary and sufficient condition has been provided, under which the adversary can uniquely obtain the knowledge of the underlying physical *** the defender's perspective, a secure controller design—which exhibits a low rank structure—is proposed which renders the system unidentifiable to the adversary, while trading off the control system's performance. Finally, a numerical example has been provided to demonstrate the effectiveness of the proposed secure controller design.
