SYSTEM AND METHOD OF MASKING ELECTROMAGNETIC INTERFERENCE (EMI) EMISSIONS OF A CIRCUIT
First Claim
1. A system comprising:
- a random number generator which matches a frequency of a circuit to be protected, and which generates a random signal to be superimposed on data;
a low noise amplifier which receives the random signal from the random number generator; and
an antenna which receives the random signal from the low noise amplifier and transmits the random signal to mask the data of the circuit to be protected.

Abstract
A system is provided for securing information residing on a circuit (e.g., processor). In particular, a system and method is provided for masking electromagnetic interference (EMI) emissions emitting from a circuit using a random noise generator in combination with a low noise amplifier and antenna. The random number generator matches a frequency of a circuit to be protected, and generates a random signal to be superimposed on data. The low noise amplifier receives the random signal from the random number generator, and an antenna receives the random signal from the low noise amplifier and transmits the random signal to mask the data of the circuit to be protected.
