”FRIEND-FOE” IDENTIFICATION SYSTEM BASED ON A ZERO-DISCLOSURE AUTHENTICATION PROTOCOL Russian patent published in 2022 - IPC G01S13/78 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and can be used to determine the nationality of mobile objects and their identification. The expected result is achieved by the fact that two switching blocks are introduced into the ‘friend-foe” identification system, consisting of two parts placed on the respondent and the requester, in the part placed on the respondent, the use of which makes it possible to calculate the noisy parameters U*(i), S*(i) and T*(i) using one adder modulo q, where q is the number generating the multiplicative group, and one adder memory block, where the noise values ΔU(i), ΔS (i), ΔT (i) of the parameter values U, S(i) and T(i) are stored, respectively.

EFFECT: reduction in circuit costs for the implementation of the identification process.
