Abstract

Physical and side channel attacks on Internet of Things (IoT) devices employing cryptographic software are an increasing threat to the security of the Internet. Preventing these attacks may require new, hardware-based approaches to encryption. Here, we present a possible solution, consisting of a multimodal metal-insulator-metal (MIM) plasmonic ring resonator-based Physically Unclonable Function (PUF). Device-specific field distribution patterns with strong sub-wavelength confinement act as a device-specific cryptographic identifier to ensure private communications. This is possible because our MIM structures are ultra-responsive to fabrication variations, such as sidewall roughness, metal/insulator thicknesses, coupling lengths, ring diameters, and material impurities.
