COVID-19 And Cybersecurity: Pay Attention To Exponential Growth!
By Andreas Kuehlmann - 08 Mar, 2021 - Comments: 0

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

Design Issues For Chips Over Longer Lifetimes
By Ed Sperling - 08 Mar, 2021 - Comments: 0

Semiconductor Engineering sat down to discuss the myriad challenges associated with chips used in complex systems over longer periods of time them with Jean-Marie Brunet, senior director for the Emulation Division at Siemens EDA; Frank Schirrmeister, senior group director for solution marketing at Cadence; Maurizio Griva, R&D Manager at Reply; and Laurent Maillet-Contoz, system and architec... » read more

Water System Hack And The Implications For Hardware Security
By John Hallman - 04 Mar, 2021 - Comments: 0

Last month we talked about the SolarWinds hack and now this month another disturbing attack has taken place – this time on a water supply system in Florida. Unfortunately, these types of attacks are becoming more frequent, giving us all pause as to how secure the systems that serve our everyday life really are. What lessons can we take from this recent attack that we can implement to make thi... » read more

Auto OEMs Face New Competitive Threats
By Ann Mutschler - 04 Mar, 2021 - Comments: 0

Automotive design and manufacturing are undergoing a fundamental shift to the left as cars increasingly are electrified and chips take over more functions formerly done by mechanical parts, setting the stage for massive disruption across a supply chain that has been in place for decades. The success of Tesla — a company that had never actually built a chip or a car — was both a surprise ... » read more

Keeping Key Management Clear And Physical
By Denis Pochuev - 04 Mar, 2021 - Comments: 0

Fundamental to all digital security systems is the ability to turn sensitive data into what looks like random incomprehensible jibberish and turn it back again into the same original information. But that is not all there is to it. You should be able to do that second bit of getting the original text only if you are allowed to do so. A classic way to deal with this problem is by using another s... » read more

Security Provisioning Moves Out Of The Factory
By Bryon Moyer - 04 Mar, 2021 - Comments: 1

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

A Machine-Learning-Resistant 3D PUF with 8-layer Stacking Vertical RRAM and 0.014% Bit Error Rate Using In-Cell Stabilization Scheme for IoT Security Applications
By Technical Paper Link - 03 Mar, 2021 - Comments: 0

Abstract: "In this work, we propose and demonstrate a multi-layer 3-dimensional (3D) vertical RRAM (VRRAM) PUF with in-cell stabilization scheme to improve both cost efficiency and reliability. An 8-layer VRRAM array was manufactured with excellent uniformity and good endurance of >10 7 . Apart from the variation in RRAM resistance, enhanced randomness is obtained thanks to the parasitic IR... » read more

Security In FPGAs And SoCs
By Ed Sperling - 23 Feb, 2021 - Comments: 0

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
By David Maidment - 11 Feb, 2021 - Comments: 0

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
By Bryon Moyer - 10 Feb, 2021 - Comments: 0

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
