Physically unclonable functions (PUFs) and true random number generators (TRNGs) are
cryptographic primitives very well suited for secure IoT devices. This article proposes a …

Physical unclonable functions (PUFs) are excellent candidates to generate secret
information on-chip without the need for secure storage. Ring-oscillator (RO) based PUFs …

Physical unclonable functions (PUFs) are a strong and secure root source for identification
and authentication applications. PUFs are especially valuable in FPGA-based systems …

Physical unclonable function (PUF) is a promising security primitive. Most existing delay
based PUF designs are independent of the original circuit. The extra PUF circuitry not only …

This paper describes a circuit structure named RO-PUF-TRNG based on ring oscillators
(ROs), which is able to be calibrated to perform as a physically unclonable function (PUF) …

The research into ring oscillator physically unclonable functions (RO-PUF) continues to
expand due to its simple structure, ease of generating responses, and its promises of …

Abstract Process variations within Field Programmable Gate Arrays (FPGAs) provide a rich
source of entropy and are therefore well-suited for the implementation of Physical …

Reconfigurable Scan Networks (RSNs) are a powerful tool for testing and maintenance of
embedded systems, since they allow for flexible access to on-chip instrumentation such as …

The main issue of ring oscillator physical unclonable functions (RO-PUF) is the existence of
unstable ROs in response to environmental variations. The RO pairs with close frequency …

The ring oscillator physically unclonable function (ROPUF) is one of the several types of
PUF that has great potential to be used for security purposes. An alternative ROPUF design …
