PUF Probe: A PUF-based Hardware Authentication Equipment for IEDs. (arXiv:2307.15338v1 [cs.CR])

Intelligent Electronic Devices (IEDs) are vital components in modern
electrical substations, collectively responsible for monitoring electrical
parameters and performing protective functions. As a result, ensuring the
integrity of IEDs is an essential criteria. While standards like IEC 61850 and
IEC 60870-5-104 establish cyber-security protocols for secure information
exchange in IED-based power systems, the physical integrity of IEDs is often
overlooked, leading to a rise in counterfeit and tainted electronic products.
This paper proposes a physical unclonable function (PUF)-based device (IEDPUF …
