This disclosure describes techniques for analyzing statistical quality of bitstrings produced by a physical unclonable function (PUF). The PUF leverages resistance variations in the power grid wires of an integrated circuit. Temperature and voltage stability of the bitstrings are analyzed. The disclosure also describes converting a voltage drop into a digital code, wherein the conversion is resilient to simple and differential side-channel attacks.

Systems and methods for analyzing stability using metal resistance variations

Authentication that leverages a Physical Unclonable Function (PUF) to generate bitstrings, session keys and long-lived keys (LLK).

System and methods for PUF-based authentication

The invention is directed to an autonomous, self-authenticating and self-contained secure boot-up system and methods for field programmable gate arrays (FPGAs) that leverages physical unclonable functions (PUFs).

Autonomous, self-authenticating and self-contained secure boot-up system and methods

A side-channel attack countermeasure that leverages implementation diversity and dynamic partial reconfiguration as mechanisms to reduce correlation in the power traces measured during a differential power analysis (DPA) attack. The technique changes the underlying hardware implementation of any encryption algorithm using dynamic partial reconfiguration (DPR) to resist side-channel-based attacks.
