EPUF: A Novel Scheme Based on Entropy Features of Latency-based DRAM PUFs Providing Lightweight Authentication in IoT Networks. (arXiv:2307.09968v1 [cs.CR])

Physical unclonable functions (PUFs) are hardware-oriented primitives that
exploit manufacturing variations to generate a unique identity for a physical
system. Recent advancements showed how DRAM can be exploited to implement PUFs.
DRAM PUFs require no additional circuits for PUF operations and can be used in
most of the applications with resource-constrained nodes such as Internet of
Things (IoT) networks. However, the existing DRAM PUF solutions either require
to interrupt other functions in the host system, or provide unreliable
responses due …
