CIRCUIT OBFUSCATION USING DIFFERING DIELECTRIC CONSTANTS

摘要

An obfuscated radio frequency circuit may be manufactured to include a metallization layer, and a dielectric layer under the metallization layer. The dielectric layer may be made up of a plurality of dielectric substrates having different dielectric constants to obfuscate functions of the circuit.

1. A method of manufacturing an obfuscated radio frequency circuit comprising:
determining what functions of a radio frequency circuit are required; and manufacturing the radio frequency circuit to have a metallization layer and a dielectric layer comprising a plurality of dielectric substrates, comprising a same width, having varying dielectric constants in order to achieve the required functions of the radio frequency circuit while obfuscating the functions of the manufactured radio frequency circuit.
