An authentication device is provided that authenticates an electronic device based on the responses from distinct types of physically unclonable functions. The authentication device receives a device identifier associated with the electronic device. It then sends one or more challenges to the electronic device. In response, the authentication device receives one or more responses from the electronic device, the one or more responses including characteristic information generated from two or more distinct types of physically unclonable functions in the electronic device.

Applying circuit delay-based physically unclonable functions (PUFs) for masking operation of memory-based PUFs to resist invasive and clone attacks

One feature pertains to generating a unique identifier for an electronic device by combining static random access memory (SRAM) PUFs and circuit delay based PUFs (e.g., ring oscillator (RO) PUFs, arbiter PUFs, etc.). The circuit delay based PUFs may be used to conceal either a challenge to, and/or response from, the SRAM PUFs, thereby inhibiting an attacker from being able to clone a memory device's response.

A method is provided for using obtaining a reproducible device identifier from a physically unclonable function. An authentication device may receive a first physically unclonable function (PUF) dataset from the electronic device, the first PUF dataset including characteristic information generated from a physically unclonable function in the electronic device. The authentication device may then identify a pre-stored PUF dataset corresponding to the electronic device. Authentication of the electronic device may be performed by correlating the pre-stored PUF dataset and the first PUF dataset for the electronic device, wherein such correlation is based on a pattern or distribution correlation the pre-stored PUF dataset and the first PUF dataset. Because such correlation is performed on datasets, and not individual points, systematic variations can be recognized by the correlation operation leading to higher correlation than point-by-point comparisons.

Physically unclonable function pattern matching for device identification

A portable self-contained node apparatus establishes a connection to a host apparatus having one or more peripheral devices connected directly thereto. The node apparatus is configured to view the one or more peripheral devices while being unaware of the host apparatus, and to act as a master device interacting directly with the one or more peripheral devices.

An inspection system positions a balancing shim to asymmetrically balance a magnetic field generated by an inductive sensor, which forms part of the inspection system. Additionally, relays and capacitors used to tune the inductive sensor to a desired resonance frequency are geometrically arranged to minimize electrical interference generated by operation of the relays and capacitors. A shielding device, which may be formed on a printed circuit board, protects a magnetic field generated by the inductive sensor from external electromagnetic interference. A slot positioned in the inductive sensor may be used to tune a resonant mode of the inductive sensor to accurately and particularly detect metallic shanks and/or other metallic objects in shoes, socks, and/or clothing.
