Graphene-based PUFs that are reconfigurable and resilient to ML attacks


Researchers at Pennsylvania State University propose using graphene to create physically unclonable functions (PUFs) that are energy efficient, scalable, and secure against AI attacks. Abstract "Graphene has a range of properties that makes it suitable for building devices for the Internet of Things. However, the deployment of such devices will also likely require the development of s... » read more

Is There a Practical Test For Rowhammer Vulnerability?


Rowhammer is proving to be a difficult DRAM issue to fix. While efforts continue to mitigate or eliminate the effect, no solid solution has yet made it to volume production. In addition, more aggressive process nodes are expected to exacerbate the problem. In the absence of a fix, then, testing may be one way to give DRAM manufacturers and users some way to segregate devices that are more su... » read more

IC Security Threat Grows As More Devices Are Connected


Designing for security is beginning to gain traction across a wider swath of chips and systems as more of them are connected to the Internet and to each other, sometimes in safety- and mission-critical markets where the impact of a cyber attack can be devastating. But it's also becoming more difficult to design security into these systems. Unlike in the past, connectivity is now considered e... » read more

COVID-19 And Cybersecurity: Pay Attention To Exponential Growth!


COVID-19 and cybersecurity – you may wonder what these two seemingly very different topics have in common. I would list two: Both of them are exponential in nature, which, as a society we have difficulties grappling with – making this one of the reasons for our uneven responses. Both of them require a multi-layered solution strategy that, while it does not need to be perfect, must b... » read more

Security Provisioning Moves Out Of The Factory


Security credentials traditionally have been provisioned during chip manufacturing, often as a final part of the testing process. That's starting to change. Logistics management can be improved by pushing that process out — even as far as the on-boarding process. And simpler on-boarding can hide most of the details from the user. “The IT approach to provisioning IoT devices has primar... » read more

Security In FPGAs And SoCs


Chip security is becoming a bigger problem across different markets, with different emerging standards and more sophisticated attacks. Jason Moore, senior director of engineering at Xilinx, talks with Semiconductor Engineering about current and future threats and what can be done about them. » read more

Certification And Collaboration Key To Closing IoT Security-Perception Gap


When it comes to security today, there’s perception and then there’s cold, hard reality. Here’s the reality: Cybersecurity Ventures expects global cybercrime costs to grow by 15% per year over the next five years, reaching $10.5 trillion annually by 2025, which is triple the 2015 figure. To get a sense for how pervasive the problem is, Symantec set up a “honeypot” system that dete... » read more

DRAM’s Persistent Threat To Chip Security


A well-known DRAM vulnerability called "rowhammer," which allows an assailant to disrupt or take control of a system, continues to haunt the chip industry. Solutions have been tried, and new ones are being proposed, but the potential for a major attack persists. First discovered some five years ago, most of the efforts to eliminate the "rowhammer" threat have done little more than mitigate t... » read more

Longer Chip Lifecycles Increase Security Threat


The longer chips and electronic systems remain in use, the more they will need to be refreshed with software and firmware updates. That creates a whole new level of security risks, ranging from over-the-air intercepts to compromised supply chains. These problems have been escalating as more devices are connected to the Internet and to each other, but it's particularly worrisome when it invol... » read more

SolarWinds Attack Is A Cautionary Tale For Hardware And Its Supply Chain


The recent SolarWinds hacking incident that left many Fortune-500 companies and US government networks exposed is an interesting cautionary tale for unchecked software and hardware supply chain security vulnerabilities. The highly sophisticated software supply chain attack occurred in the SolarWinds Orion IT monitoring system. This system, used by over 33,000 companies, monitors performance acr... » read more
