FIELD: cryptography.
SUBSTANCE: invention relates to secure information networks with quantum distribution of cryptographic keys. In this method unidirectional key transport is used with total number of N nodes in the network, where each node has c links; if probability of successful attack ps is less than required value of key transport resistance, then reducing requirements for quantum key distribution protocols p of each connection between nodes, leaving ps less than the required value of key transport resistance, controlling the key transport parameter c.
EFFECT: providing the possibility of controlling the stability criterion of quantum key distribution protocols to ensure the use of the minimum possible amount of resources, required for a given level of network infrastructure resistance.
