2023年12月7日 · 物理不可克隆函数（Physical Unclonable Function，PUF）是一种利用物理随机性创建唯一ID密钥的技术。 它基于硬件的随机特性，使得每个设备都有独特的指纹或ID，而这些ID很难被复制或克隆。
Physical unclonable function - Wikipedia
A physical unclonable function (sometimes also called physically-unclonable function, which refers to a weaker security metric than a physical unclonable function [citation needed]), or PUF, is a physical object whose operation cannot be reproduced ("cloned") in physical way (by making another system using the same technology), that for a given ...
In this context, Physically Unclonable Functions (PUFs) constitute an excellent secure alternative to provide secure key generation and storage. The idea behind a PUF is to use uncontrollable physical variations introduced during the manufacturing process to create physical entities with a unique and uncontrollable behavior.
什么是物理不可克隆（PUF）？为何是解决芯片安全的绝佳方法？
2021年7月19日 · 物理不可克隆功能 (puf) 是一种硬件安全技术，它利用固有的设备变化来对给定的输入产生不可克隆的唯一设备响应。 在更高的层面上，PUF 可以被认为类似于人类的生物识别——它们是每一块硅的固有和唯一标识符。

基于传播时延的puf 数字信号的传播会受到MOSFET通道长度、宽度和阈值电压、氧化层厚度、金属线的形状等各种因素的影响，延迟将会有部分随机性。 典型代表有基于仲裁器的PUF [10] 、基于 环形振荡器 的PUF [11] 和基于毛刺的PUF [12] 。
An Introduction to Physically Unclonable Functions
2021年6月14日 · What Is a PUF? Physically unclonable functions (PUFs) are a technique in hardware security that exploits inherent device variations to produce an unclonable, unique device response to a given input. On a higher level, a PUF can be thought of as analogous to biometrics for humans – they are inherent and unique identifiers for every piece of ...
A Physical Random Function or Physical Unclonable Function (PUF) is a function that is: ÐBased on a physical system ÐEasy to evaluate (using the physical system) ÐIts output looks like a random function ÐUnpredictable even for an attacker with physical access
Physical unclonable function: architectures, applications and ...
2020年3月19日 · Physical unclonable function (PUF) is hardware-specific security primitive for providing cryptographic functionalities that are applicable for secure communication among the embedded devices. The physical structure of PUF is considered to be easy to manufacture but hard or impossible to replicate due to variations in its manufacturing process.
Physical Unclonable Function A Physical Unclonable Function (PUF) is a function that is: – Based on a physical system – Easy to evaluate (using the physical system) – Hard to predict A PUF can additionally be: • Manufacturer Resistant (better than unclonable: even the manufacturer cannot produce two identical systems)
