| Abstract: |
| The identity authentication of internet-connected devices is the basis for secure operation of industrial Internet and Internet of Things.This paper analyzes the characteristics of Physical Unclonable Function(PUF) as the identity credentials of the networked devices,and establishes a multi-layered metrics system for its performance in which three types of metrics(necessary metrics,important metrics and application metrics) are classified according to the importance of performance metrics.Each indicator and its evaluation method are explained,and a comprehensive evaluation scheme which can be provided for PUF selection is given.The experimental results show that the PUF performance metrics system and evaluation scheme are feasible in engineering. |
