Making PUFs Even More Secure

As security has become a must-have in most systems, hardware roots of trust (HRoTs) have started appearing in many chips. Critical to an HRoT is the ability to authenticate and to create keys – ideally from a reliable source that is unviewable and immutable. “We see hardware roots of trust deployed in two use models — providing a foundation to securely start a system, and enabling a se... » read more

A Novel Complementary Architecture of One-time-programmable Memory and Its Applications as Physical Unclonable Function (PUF) and One-time Password

Abstract "For the first time, we proposed a 2T complementary architecture of one-time-programmable memory (OTP) in a foundry logic CMOS chip. It was then used to realize the PUF (Physical unclonable function), and the combination with the AI technology to provide a one-time password capability. At first, an OTP was developed based on a novel 2T CMOS unit cell. The experimental results show t... » read more

The MCU Dilemma

The humble microcontroller is getting squeezed on all sides. While most of the semiconductor industry has been able to take advantage of Moore's Law, the MCU market has faltered because flash memory does not scale beyond 40nm. At the same time, new capabilities such as voice activation and richer sensor networks are requiring inference engines to be integrated for some markets. In others, re... » read more

IP Requirements Changing

Twenty years ago the electronics industry became interested in the notion of formalizing re-use through third-party IP. It has turned out to be harder than anyone imagined. In 1996, the Virtual Socket Interface Alliance ([getentity id="22845" comment="VSIA"]) was formed to standardize the development, distribution and licensing of IP. Soon afterward, companies with a couple of people in a ga... » read more

Changes In Chip Design

We all know that sub-10nm is coming. But is that really what will define the next generation of semiconductors? Progress in semiconductor technology increasingly is not just about advancements in the hardware. It also involves advancements in applications and technologies peripheral to the devices themselves. That may sound counterintuitive, but going forward the technology, applications and... » read more
