KEY JOINT USAGE DEVICE AND THE SYSTEM FOR ITS CONFIGURATION Russian patent published in 2017 - IPC H04L9/08 G06F21/62 

FIELD: radio engineering, communication.

SUBSTANCE: system for the network device configuring for the key joint usage, containg: means for obtaining the key material for getting personal module in electronic form (122, p₁), the open module (110, N) and the symmetric polynomial (124, f₁) from two variables, having integral coefficients, at that the binary representation of the open module and the binary representation of the individual module are identical in at least in consecutive bits of the key length (b), generator (200) for generating the local key material for the network device, containing: network devices control means (250) to obtain the identification number (A) in electronic form for the network device and for the electronic storing of the generated local key material in the network device and storing the open module in the network device, and the polynomial manipulation device (240) to determe the polynomial from one variable from the polynomial from two variables by substituting the identification number in the polynomial from two variables, reduction of the substitution result according to the personal module.

EFFECT: security provision between two network devices by key joint usage.
