Giga-ID: Device Enrollment & Authentication

The Giga-ID is for customers who need to authenticate devices using hardware root-of-trust in all environments, but especially in remote edge devices and applications.

The Giga-ID is also ideal for customers who need devices with built in anti-counterfeiting protection, ensuring that a device is authentic and correctly sourced.

Giga-ID Enrollment

PUF circuits receive a sequence of bits as input (called challenges). Based on the input, a PUF generates a sequence of bits as output (called responses). The combination of the challenge and response is call a Challenge Response Pair (CRP).

Given sufficient CRPs, no two chips can generate identical responses to all the challenges due to the manufacturing variability, allowing unique identification of the chip. This serves as an anti-counterfeiting mechanism for all chips with Giga-ID.

Giga-ID Authentication

Step 1: Enrollment – a circuit with a PUF connects directly to a server. The server sends challenges, PUF sends responses. Server stores the CRP in a table. Then the circuit is mounted to a device.

Step 2: Authentication – the server sends arbitrary PUF challenge(s) to the device, the PUF sends response(s). If result matches the enrollment result for a particular challenge, device is authenticated.
