METHOD OF ENCODING AND ENCRYPTION KEYS TRANSMISSION Russian patent published in 2008 - IPC H04L1/08 H04L9/08 

FIELD: information encryption.

SUBSTANCE: method includes forming quantum photonic status sequence on the transmitting station to encode encryption keys and transmission of these statuses via open space to receiving station; at that, the distance between the stations is previously measured and clock on both station is synchronised; then, transmitting station converts quantum photonic statuses to one- or multiphoton orthogonal statuses and measures their sending time, which is sent to receiving station; the receiving station measures receiving time of the one- or multiphotonic quantised statuses, determines delay value, using which decoding and eavesdropping are performed.

EFFECT: provision of encryption key security during its long-distance transmission via open space, provision of long-term stability and reducing error stream in transmitted encryption keys on receiving station.
