PUF技术（一种硬件安全技术）_百度百科 PUF技术（物理不可克隆功能）是基于半导体制造工艺波动产生的物理特性差异生成芯片唯一指纹的硬件安全技术，由 麻省理工学院 R S Pappu博士于2002年提出。
Physical unclonable function - Wikipedia A PUF is a physical entity embodied in a physical structure PUFs can be implemented in integrated circuits, including FPGAs, [4] and can be used in applications with high-security requirements, more specifically cryptography, Internet of things (IOT) devices [5] and privacy protection [6]
PUF | PUFsecurity | PUF-based Security IP Solutions A PUF can provide a safeguarded source for both a Unique Identifier (UID) and or Hardware Unique Key (HUK) The UID is used for device identification, and the HUK is mainly used to derive other secret keys (as a keying source)
