什么是独特的?
有各种各样的PUF技术,但是大多数都是使用能动电路实现的,这些器件对PVT(工艺、电压、温度)变化很敏感,并且会有老化效应。为了克服这个问题必须引入ECC逻辑纠错功能。
The are various PUF technologies, but most of them are implemented using active devices,which are sensitive to PVT (process,voltage,temperature)changes and are accompanied by an aging effect. To overcome this, an ECC (Error Correction Code) logic function must be additionally introduced.
