Latest Patents

Yijian's latest patents include the following:

1. **Challenge Screening Method for Improving Stability of Strong Physical Unclonable Function**

This invention describes a novel challenge screening method aimed at enhancing the stability of strong PUFs. By quantifying the stability of a group of challenges (GOCs) as either stable (1) or unstable (0), a challenge-stability pair (CSP) is created. Through a machine learning training dataset utilizing these CSPs, a screening model is developed. This model determines the challenge stability of strong PUFs and effectively filters out stable challenges, ultimately improving stability against external disturbances.

2. **Software PUF Based on RISC-V Processor for IoT Security**

In this patent, Yijian has disclosed a software PUF using a 32-bit RISC-V processor designed to bolster IoT security. The processor generates abnormal information in a low voltage operating state, which is then compared to normal results to create 5-bit binary data characterized by high randomness and uniqueness. This innovation makes it extremely difficult for potential attacks to penetrate the internal mechanisms of the processor, thereby securing IoT applications.
