| 摘要 |
Embodiments include apparatuses, methods, and systems for a physically unclonable function (PUF) circuit. The PUF circuit may include an array of PUF cells to generate respective PUF bits of an encryption code. Individual PUF cells may include first and second inverters cross-coupled between a bit node and a bit bar node. Features and techniques of the PUF cells are disclosed to improve the stability and/or bias strength of the PUF cells, to generate a dark bit mask for the array of PUF cells, and to improve resilience to probing attacks. Other embodiments may be described and claimed. |
