CHECKING SYNCHRONISATION FOR DEVICE AUTHENTICATION Russian patent published in 2011 - IPC H04L29/06 

FIELD: information technology.

SUBSTANCE: device authentication is based on the ability of a person to synchronise finger movement. That way, the procedure of forming a pair for two wireless devices may include checking synchronisation which is based on relative time for activating input devices on each of the wireless devices. Checking synchronisation involves determining whether user input devices have been activated on two different wireless devices within a given time interval. Checking synchronisation involves comparing time intervals given by several activated user input devices on two wireless devices. When checking synchronisation after receiving the last reading associated with the input device activation time, any readings, preferably representing one input device activation time, are rejected.

EFFECT: high level of cryptographic security.
