METHOD FOR INFORMATION PROTECTION OF DISTRIBUTED RANDOM ANTENNA Russian patent published in 2012 - IPC H04K3/00 

FIELD: physics, communications.

SUBSTANCE: invention relates to protection of confidential information and can be used to protect radio systems associated with the term "distributed random antennae". The method for information protection of a distributed random antenna involves connecting interference generators to the distributed random antenna through N interface devices, said interference generators providing information protection for the distributed random antenna. M of the N interface devices include M≤N amplitude modulators which, under the action of M interference generators, perform joint random amplitude modulation of information signals and interference emitted by the distributed random antenna.

EFFECT: high efficiency of protecting a distributed random antenna on confidential information leakage channels, as well as high ecological cleanness of the protection system owing to low power of the electromagnetic interference used.
