在本文中，我们将讨论 PUF（ physically unclonable functions） 物理不可克隆功能，以及它如何提高 IC 的硬件安全性。 在一个严重依赖电子产品的日益互联的世界中，安全性至关重要。现代电子产品几乎一致地依赖密…

2024年4月13日 · Here, we demonstrate all-silicon multidimensionally-encoded optical PUFs fabricated by integrating silicon (Si) metasurface and erbium-doped Si quantum dots (Er-Si QDs) with a CMOS-compatible ...

2020年3月19日 · In this study, the authors have thoroughly explored the architecture, applications, requirements, and challenges of PUF that provide security solutions. For presenting the literature, they have designed a taxonomy where PUFs are divided under two main categories, including non-silicon and silicon-based PUF.

2020年2月24日 · We focus here on the optical PUF as a representative example of non-silicon PUFs, arbiter PUF (APUF) as an example of time-delay based silicon PUFs, and static random-access memory PUF (SRAM...

This paper describes the use of physical unclonable functions (PUFs) in low-cost authentication and key generation applications. First, it motivates the use of PUFs versus conventional secure nonvolatile memories and defines the two primary PUF types: “strong PUFs” and “weak PUFs.”

2022年6月1日 · Consequently, PUFs are inexpensive to fabricate, prohibitively challenging to duplicate, admit no compact mathematical representation, and are intrinsically tamper-resistant. This manuscript gives a complete survey of PUFs as a promising research field in security with a wide application, especially with connected devices.
