“…However, they are not necessarily the most recent. In [28][29][30], promising MRAM-based PUF results are reported. However, the reported results are based on simulation studies, which do not fully capture the physical reality.…”

“…In [10], the results are based on small-scale experiments on STT-MRAM while our results are based on larger-scale analyses. For using the MRAM-based PUFs in key generation protocols [28][29][30], it is necessary to employ some error reduction/correction methods for enhancing the PUF reliability. Our results show 49.8% of the inter-PUF between different TAS-MRAM-based PUF dies.…”

“…For example, the magnetoresistive random-access memory (MRAM) PUF, the dynamic random access memory (DRAM), PUF, and the memristive device based strong PUF (mrSPUF). MRAM PUF responses are generated using the unique energy-tilt, which is an outcome of the random geometric variations in the MRAM cells [14]. Their solution requires only minimal hardware and current drivers beyond conventional MRAM to supply the destabilizing current.…”

New Security Improvements in Next-Generation Passive Optical Networks Stage 2 †

Passive optical networks are currently the most promising solution for access networks. These networks rely on broadcast signal distribution in the downstream direction and unicast signal transmission in the upstream direction. The upstream direction is controlled by optical line termination (OLT). The broadcast transmission method increases security vulnerability because the attacker is able to connect his/her modified optical network unit (ONU) to the free port of the splitter (commonly in the basement). We present the concept for the activation process of ONUs based on physical unclonable function (PUF) for next-generation passive optical networks stage 2 (NG-PON2). The use of PUF increases security in the NG-PON2. Furthermore, the registration identifier (ID) is not stored in a nonvolatile memory, in comparison with the common solution defined by the International Telecommunication Union (ITU) recommendation G.989.3. An attacker cannot perform a reverse engineering attack to obtain the registration ID. For this reason, the attacker cannot clone an ONU. We proposed security improvements that involve authentication, encryption, integrity protection, and data origin verification methods in the NG-PON2. Our model uses the standard implementation of the transmission convergence layer of NG-PON2 with the new physical layer operations, administration, and maintenance (PLOAM) messages. The recommendation G.989.3 allows specifying own PLOAM messages since not all IDs are used in the current specification.

“…PUF, broadly categorized as “weak PUF” and “strong PUF”, is an emerging low-cost on-chip secure primitive [ 2 , 4 , 5 , 6 , 7 ]. By converting the inherent uncontrollable and unpredictable variations of the semiconductor manufacturing process to a random digital bit string, a PUF generates a “response” upon a “challenge”, namely a challenge-response pair (CRP).…”

Authentication is a crucial security service for the wireless sensor networks (WSNs) in versatile domains. The deployment of WSN devices in the untrusted open environment and the resource-constrained nature make the on-chip authentication an open challenge. The strong physical unclonable function (PUF) came in handy as light-weight authentication security primitive. In this paper, we present the first ring oscillator (RO) based strong physical unclonable function (PUF) with high resilience to both the electromagnetic (EM) side-channel attack and the support vector machine (SVM) modelling attack. By employing an RO based PUF architecture with the current starved inverter as the delay cell, the oscillation power is significantly reduced to minimize the emitted EM signal, leading to greatly enhanced immunity to the EM side-channel analysis attack. In addition, featuring superior reconfigurability due to the conspicuously simplified circuitries, the proposed implementation is capable of withstanding the SVM modelling attack by generating and comparing a large number of RO frequency pairs. The reported experimental results validate the prototype of a 9-stage RO PUF fabricated using standard 65 nm complementary-metal-oxide-semiconductor (CMOS) process. Operating at the supply voltage of 1.2 V and the frequency of 100 KHz, the fabricated RO PUF occupies a compact silicon area of 250 µm 2 and consumes a power as low as 5.16 µW per challenge-response pair (CRP). Furthermore, the uniqueness and the worst-case reliability are measured to be 50.17% and 98.30% for the working temperature range of −40∼120 • C and the supply voltage variation of ±2%, respectively. Thus, the proposed PUF is applicable for the low power, low cost and secure WSN communications.
