FIELD: information protection.
SUBSTANCE: invention relates to the field of protection of confidential information; it can be used to protect radio engineering systems united by a term “distributed random antennas”. The proposed method for protecting distributed random antennas consists in the fact that it includes placing devices near the distributed random antenna that ensure the absorption of the electromagnetic field power of a confidential information signal, where small-sized resonant receiving antennas with the active load are used as the specified devices.
EFFECT: increased efficiency of protecting a distributed random antenna from leakage of confidential information.
