Title: Innovations of Xilong Shao in PUF Circuit Design

Introduction

Xilong Shao is a notable inventor based in Zhejiang, China. He has made significant contributions to the field of circuit design, particularly in the development of physically unclonable functions (PUFs). With a total of two patents to his name, Shao's work focuses on enhancing security and efficiency in electronic systems.

Latest Patents

Shao's latest patents include a PUF circuit based on the threshold loss of MOSFETs. This innovative circuit comprises N stages of delay units and an arbiter. Each stage of the delay unit consists of six inverters and four MOS transistors, which can be either PMOS or NMOS transistors. By utilizing only one PMOS or NMOS transistor in each path, the design reduces hardware costs while increasing the delay difference between signals, thereby enhancing randomness.

Another significant patent is the machine learning attack resistant strong PUF with a dual-edge sampling function. This invention includes switch units, a first arbiter, and a second arbiter. The first arbiter determines the sequential order of delays at the rising edge of input signals, while the second arbiter does so at the falling edge. The design of the switch units, composed of eight MOS transistors, allows for high resistance against machine learning attacks and minimizes hardware expenditure.
