INFORMATION SECURITY APPARATUS FOR DISTRIBUTED RANDOM ANTENNA Russian patent published in 2013 - IPC H04K3/00 

FIELD: radio engineering, communication.

SUBSTANCE: information security apparatus for a distributed random antenna, which is protected via a linear noise masking technique, has a multiplicative jamming device, a modulating signal former and a controlled parametric device, having a variable active resistance. The output of the multiplicative jamming device is connected to the input of the modulating signal former, the output of which is connected to the control input of the parametric device, which is connected to the distributed random antenna which is protected via a linear noise masking technique to facilitate amplitude modulation of the mixture of the confidential information signal and additive noise in the distributed random antenna which is protected via a linear noise masking technique.

EFFECT: high efficiency of protecting a distributed random antenna on confidential information leakage channels.
