Vehicle Security: Post-Quantum Security to the CAN Network


This new technical paper titled "PUF-Based Post-Quantum CAN-FD Framework for Vehicular Security" is published by researchers at University of Tennessee. Abstract "The Controller Area Network (CAN) is a bus protocol widely used in Electronic control Units (ECUs) to communicate between various subsystems in vehicles. Insecure CAN networks can allow attackers to control information between vit... » read more

Research Bits: June 21


Side-channel protection for edge AI Researchers from the Massachusetts Institute of Technology built a chip that can defend against power side-channel attacks targeting machine learning computations in smartwatches, smartphones, and tablets. Side-channel attacks involve observing a facet of the device's operation, in this case power, to deduce secrets. “The goal of this project is to buil... » read more

Key Recovery for Content Protection Using Ternary PUFs Designed with Pre-Formed ReRAM


RESEARCH PAPER Abstract "Physical unclonable functions, embedded in terminal devices, can be used as part of the recovery process of session keys that protect digital files. Such an approach is only valuable when the physical element offers sufficient tamper resistance. Otherwise, error correcting codes should be able to handle any variations arising from aging, and environmentally induce... » read more

A Novel PUF Using Stochastic Short-Term Memory Time of Oxide-Based RRAM for Embedded Applications


Abstract: "RRAM suffers from poor retention with short-term memory time when using low compliance current for programing. However, the short-term memory time exhibits ideal randomness, which can be exploited as an entropy source for physically unclonable function (PUF). In this work, we demonstrated a novel PUF utilizing the stochastic short-term memory time of oxide-based RRAM. The proposed P... » read more

Hybrid Boolean Networks as Physically Unclonable Functions


Abstract: "We introduce a Physically Unclonable Function (PUF) based on an ultra-fast chaotic network known as a Hybrid Boolean Network (HBN) implemented on a field programmable gate array. The network, consisting of N coupled asynchronous logic gates displaying dynamics on the sub-nanosecond time scale, acts as a `digital fingerprint' by amplifying small manufacturing variations during a peri... » read more

How Physically Unclonable Function (PUF) Technology Protects Embedded Systems


Security experts have been excited about the promise of physically unclonable function (PUF) technology for many years. It wasn't until recently, however, that reliable, cost-effective ICs with integrated PUF technology became available on the market. What's driving all of the excitement over PUF? In this white paper, I'll demystify PUF and highlight how it benefits a variety of embedded system... » read more

IP Security In FPGAs


Quinn Jacobson, strategic architect at Achronix, talks about security in FPGAs, including how to prevent reverse engineering of IP, how to make sure the design is authentic, and how to limit access to IP in transit and in the chip. » read more

System Bits: Feb. 26


Firefly microstructures in LED light bulbs Pennsylvania State University researchers wanted to improve the energy efficiency of commercial light-emitting diode light bulbs to save even more energy. They found the answer in the lantern surface of fireflies. "LED lightbulbs play a key role in clean energy," said Stuart (Shizhuo) Yin, professor of electrical engineering at Penn State. "Overall... » read more

Blockchain May Be Overkill for Most IIoT Security


Blockchain crops up in many of the pitches for security software aimed at the industrial IoT. However, IIoT project owners, chipmakers and OEMs should stick with security options that address the low-level, device- and data-centered security of the IIoT itself, rather than the effort to promote blockchain as a security option as well as an audit tool. Only about 6% of Industrial IoT (IIoT) p... » read more

Imperfect Silicon, Near-Perfect Security


Some chipmakers, under pressure to add security to rapidly growing numbers of IoT devices, have rediscovered a "fingerprinting" technique used primarily as an anti-counterfeiting measure. [getkc id="227" kc_name="Physically unclonable functions"] (PUFs) are used to assign a unique identification number based on inconsistencies in the speed with which current causes a series of logic gates to... » read more
