Learning ISO 26262 – 2nd Edition
By Kurt Shuler - 07 Dec, 2020 - Comments: 0

You might think that when you get into a debate with a customer or a supplier about the exact interpretation of some aspect of ISO 26262, all you have to do is go to the standard, look it up, and there’s the answer you all need, plain as day. That would be ideal but often doesn’t reflect reality. To realize why, you have to understand the background to the standard. A short ISO 26262 o... » read more

Edge Inference Applications And Market Segmentation
By Geoff Tate - 03 Dec, 2020 - Comments: 0

Until recently, most AI was in data centers/cloud and most of that was training. Things are changing quickly. Projections are AI sales will grow rapidly to tens of billions of dollars by the mid 2020s, with most of the growth in edge AI inference. Data center/cloud vs. edge inference: What’s the difference? The data center/cloud is where inference started on Xeons. To gain efficiency, much ... » read more

A New Method For Electrical Systems Design
By Nigel Hughes - 03 Dec, 2020 - Comments: 0

Electrical system complexity is reaching a tipping point across industries, from modern passenger vehicles to sophisticated industrial machines that can now contain nearly 5,000 wiring harnesses. The electrical systems of these machines contain multiple networks, thousands of sensors and actuators, miles of wiring and tens of thousands of discrete components (figure 1). Designing these complex ... » read more

Safeguarding Automotive Electronics
By Thierry Kouthon - 03 Dec, 2020 - Comments: 0

Modern automobiles can have up to 100 Electronic Control Units (ECUs) depending on their class, make, and model, with the number of ECUs rising even higher in the case of electric vehicles. An ECU is an embedded system in the car’s electronics. They are used to control all the vehicle's functions, including engine, powertrain, transmission, brakes, suspension, dashboard, entertainment system ... » read more

Capabilities In CAP, CHERI, And Morello
By Paul McLellan - 03 Dec, 2020 - Comments: 0

At the recent Arm DevSummit, one of the presentations mentioned CHERI and the Arm Morello board in passing. This was in the context of using capabilities (perhaps) in some future Arm processors to increase the amount of memory safety, and to protect against vulnerabilities like Spectre and Meltdown. I'd never heard of either, so I was intrigued and decided to look into the details. But the f... » read more

Effective Configuration Of Security Tools
By Taylor Amerding - 03 Dec, 2020 - Comments: 0

To do a job well, you need the right tools. But it’s just as important—perhaps even more so—to use those tools correctly. A hammer will make things worse in your construction project if you’re trying to use it as a screwdriver or a drill. The same is true in software development. The intricacies of coding and the fact that it’s done by humans means that throughout the software deve... » read more

IC Integrity Of Edge-Computing Processors: Meeting The Demands Of AI
By Rob van Blommestein - 18 Nov, 2020 - Comments: 0

If you ask most people, they would say that we’re living in an age of artificial intelligence (AI). But the reality is that we’re just getting started. The age of artificial intelligence is still in its infancy. So many of aspects of our lives involve technology but we’re still having to feed that technology or manually operate that technology in order get the results we want. Autonomous ... » read more

Establishing A Special Interest Group On Common Hardware Weaknesses
By Jason Oberg - 18 Nov, 2020 - Comments: 0

It seems like almost every week yet another hardware security vulnerability is announced. Just last week a team of researchers disclosed a new attack called “Platypus”, an acronym for "Power Leakage Attacks: Targeting Your Protected User Secrets.” This is another attack exploiting the simple fact that hardware sits below the conventional security abstractions and finding a vulnerability i... » read more

Who’s Got The Hot Potato?
By Sergio Marchese - 11 Nov, 2020 - Comments: 0

In COVID-19 times, gathering a few friends in a circle and playing “hot potato” may sound like a dream. For car manufacturers and the automotive electronics supply chain, handling the cybersecurity hot potato is not quite a nightmare but certainly not a fun game. Companies like Volkswagen, Fiat, and Ford have much expertise in managing a complex supply chain and post-sale support. Most car ... » read more

Achieving Security Goals With A Hardware Root Of Trust
By Paul Karazuba - 05 Nov, 2020 - Comments: 0

In an environment of growing threats, meeting a fundamental set of security goals is imperative for safeguarding devices and data from attack. The most robust means of meeting these goals is a root of trust anchored in hardware. In Microsoft’s “The Seven Properties of Highly Secured Devices” white paper, property #1 is implementation of a hardware root of trust. As Microsoft explains: ... » read more
