INFORMATION PROTECTION METHOD FOR RANDOM ANTENNAS Russian patent published in 2021 - IPC G01R29/08 

FIELD: information security.

SUBSTANCE: invention relates to the field of confidential information (CI) protection and can be used to eliminate channels of CI leakage in radio systems, united by the term "random antennas" (RA). A method for information protection of random antennas in the conditions of an attacker using the HF intrusion method, including placing a source of a stochastic signal in the room to be protected, while in the outer loop of the HF intrusion signal generator, which includes a random antenna, a signal source containing confidential information, and other elements of the premises to be protected, near the source of the signal containing confidential information, a metallized surface should be located. Between the source of the signal containing confidential information and the metallized surface, a reaction circuit should be operated, which is controlled by the source of the stochastic signal.

EFFECT: increased efficiency of protecting the CI from leakage through the RA in the case of HF imposition, ensured protection of the CI equipment without increasing the energy level of the signal used to protect the CI.
