QUANTUM-SECURED COMMUNICATION

Method for quantum-secured communication using following encryption protocol: - Providing a pair of quantum-enabled hardware security modules (qHSM), comprising an interface to a temporarily common quantum channel, and an interface to a conventional communication channel, - Sharing a secret key (Q) with both quantum-enabled hardware security modules (qHSM) for a symmetrical encryption between both modules, wherein the secret key (Q) is obtained using quantum key distribution (100) via the common quantum channel, - Disconnecting the common quantum channel from at least one of the quantum- enabled hardware security modules (qHSM), and - Providing a communication network in which at least two nodes communicate using symmetrical encryption between the pair of quantum-enabled hardware security modules (qHSM) sharing the same secret key (Q).
