FIELD: physics.
SUBSTANCE: invention relates to a method of generating secret keys for an arbitrary pair of nodes in a computer network using a quantum key distribution system. Expansion of operational capabilities consists in increase of territorial mobility of users due to the fact that generation of a key for communication with another user can occur not only during direct connection to the control room within the controlled area through a local communication line, but also in other places outside the controlled area through an external digital data transmission network.
EFFECT: broader operational capabilities of a multi-segment QKD network while maintaining a level of safety.
