The Importance Of Memory Encryption For Protecting Data In Use
By Rocky Zhang - 05 May, 2022 - Comments: 0

Nowadays, as SoC (System-on-a-Chip) systems become more and more complex, security functions must grow accordingly to protect the semiconductor devices themselves and the sensitive information residing on or passing through them. While a Root of Trust security solution built into the SoCs can protect the chip and data resident therein (data at rest), many other threats exist which target interc... » read more

Ensuring Security By Design Is Actually Secure
By Melissa Jordan - 05 May, 2022 - Comments: 0

Today’s connected systems touch nearly every part of consumers’ lives, from smart thermostats in our homes to self-driving cars on our roads. The adoption of these new devices has led to an explosion of new semiconductors and use models. But these novel conveniences also come with new risks. With vulnerabilities on the rise and the potential for remote attacks growing, product companies mus... » read more

Hiding Security Keys Using ReRAM PUFs
By Katherine Derbyshire - 21 Apr, 2022 - Comments: 2

Resistive RAM and physically unclonable functions (PUFs) have been gaining traction for completely different reasons, but when combined they create an extremely secure and inexpensive way of storing authentication keys. As security concerns shift from purely software to a combination of hardware and software, chipmakers and systems companies have been scrambling to figure out how to prevent ... » read more

New Challenges For Connected Vehicles
By John Koon - 11 Apr, 2022 - Comments: 0

Connected vehicles are all about convenience and safety. Modern vehicles are connected to the Internet via wireless networks, consumer apps, and infotainment systems, and there is work underway to connect them over 5G to guided driving. But there also are challenges to making all of this work securely, safely, and as expected throughout the expected lifetimes of chips and systems. The goal i... » read more

Standards And Threat Testing For Secure Autonomous Vehicles
By Lee Harrison - 07 Apr, 2022 - Comments: 0

Modern vehicles continue to move up through the levels of autonomy, as defined by The Society of Automotive Engineers (SAE). These definitions have been widely adopted across the industry and emerging vehicle technology is measured against this scale (figure 1). Fig. 1: An illustration from the Society for Automotive Engineers shows levels of autonomy. The closer we move towards level... » read more

Setting The Standard For Automotive Security
By Bart Stevens - 07 Apr, 2022 - Comments: 0

Vehicle systems and the semiconductors used within them are some of the most complex electronics seen today. In the past, electronics going into vehicle systems implemented flat architectures with isolated functions controlling various components of the power train and vehicle dynamics. These electronic systems communicated primarily through legacy bus interconnect protocols, like controller ar... » read more

Add Security And Supply Chain Trust To Your ASIC Or SoC with eFPGAs
By Ralph Grundler - 07 Apr, 2022 - Comments: 0

Before Covid-induced supply chain issues affected semiconductor availability and lead times, concerns about counterfeit parts and trusted supply chains were becoming the subject of many articles and discussions affecting critical data centers, communications, public infrastructure, and facilities such as regional power plants and the grid. Today’s semiconductor design and manufacturing is com... » read more

Preventing A $500 Attack Destroying Your IoT Devices
By Rambus - 06 Apr, 2022 - Comments: 0

Internet of Things (IoT) smart devices numbering in the billions and connected via the internet are increasingly vital to society and the global economy. However, the very “connectedness” that makes IoT devices so valuable can be turned to an enormous liability if these devices are left unprotected from security-related threats. This paper explores the threat environment faced by, and the c... » read more

Common Weakness Enumeration
By Ed Sperling - 06 Apr, 2022 - Comments: 0

Understanding potential design vulnerabilities up front can help prevent future cyberattacks. Jason Oberg, CTO at Tortuga Logic, talks with Semiconductor Engineering about why CWE is so important, when it needs to be considered, and why no hardware design is completely bulletproof. » read more

Research Bits: March 22
By Jesse Allen - 22 Mar, 2022 - Comments: 0

Securing wireless communications without encryption Researchers from Princeton University, University of Michigan–Shanghai Jiao Tong University Joint Institute, and Xi’an Jiaotong University developed a millimeter-wave wireless chip that allows secure wireless transmissions and makes it challenging to eavesdrop on high-frequency wireless transmissions, even with multiple colluding bad acto... » read more
