This paper addresses the problem of the quantum networks (QN) development for secured communications through Quantum Key Distribution (QKD) protocols. The main use case for QN-based Cyber Security is related to the cryptographic key exchange using QKD for the detection of passive attacks. Starting from a brief analysis of the current achievements in QN development, a topological model of a QN is proposed, close to that of the QNs already deployed under the development. The performances of QKD applications are estimated for a simulation scenario for a case study with point-to-point QKD connections. This methodology is useful for the design of QN-based security applications, as a reliable framework for estimating the expected performances, for setting and optimization of the feasible performances. The performance issues in the quantum cryptography and QN-based Cyber Security are more challenging comparing to the conventional Cyber Security, due to the probabilistic nature of the quantum processes outputs.
