Tortuga Crosses a Chasm

Tortuga Crosses a Chasm
by Bernard Murphy on 05-29-2019 at 7:00 am

I assume you know the Geoffrey Moore “crossing the chasm” concept, jumping from early stage enthusiasts trying your product because they’ll try anything new, to expanding to a mainstream and intrinsically more critical audience – a much tougher proposition. I’d argue there may be more than one of these transitions in the… Read More


Can I Trust my Hardware Root of Trust?

Can I Trust my Hardware Root of Trust?
by Bernard Murphy on 02-28-2019 at 7:00 am

Hardware Roots of Trust (HRoTs) have become a popular mechanism to provide a foundational level of security in a cell-phone or IoT device or indeed any device that might appear to a hacker to be a juicy target. The concept is simple. In order to offer credible levels of security, any level in the stack has to be able to trust that levels… Read More


Semiconductor Security and Sleep Loss

Semiconductor Security and Sleep Loss
by Daniel Nenni on 02-11-2019 at 12:00 pm

One of the semiconductor topics that keeps me up at night is security. We track security related topics on SemiWiki and while the results are encouraging, we still have a very long way to go. Over the last three years we have published 148 security related blogs that have garnered a little more than 400,000 views. Security touches … Read More


Security and RISC-V

Security and RISC-V
by Bernard Murphy on 11-30-2018 at 7:00 am

One of the challenges in the RISC-V bid for world domination may be security. That may seem like a silly statement, given that security weaknesses are invariably a function of implementation and RISC-V doesn’t define implementation, only the instruction-set architecture (ISA). But bear with me. RISC-V success depends heavily… Read More


ARM TechCon 2018 is Upon Us!

ARM TechCon 2018 is Upon Us!
by Daniel Nenni on 10-12-2018 at 12:00 pm

ARM TechCon is one of the most influential conferences in the semiconductor ecosystem without a doubt. This year ARM TechCon has moved from the Santa Clara Convention Center to the much larger convention center in San Jose. Last year the conference seemed to be busting at the seams so this move makes complete sense. A little less … Read More


Webinar: Ensuring System-level Security based on a Hardware Root of Trust

Webinar: Ensuring System-level Security based on a Hardware Root of Trust
by Bernard Murphy on 08-23-2018 at 7:00 am

A root of trust, particularly a hardware root of trust, has become a central principle in well-architected design for security. The idea is that higher layers in the stack, from drivers and OS up to applications and the network, must trust lower layers. What does it help it to build great security into a layer if it can be undermined… Read More


Timing Channel Attacks are Your Problem Too

Timing Channel Attacks are Your Problem Too
by Bernard Murphy on 08-07-2018 at 7:00 am

You’ve heard about Meltdown and Spectre and you know they’re really bad security bugs (in different ways). If you’ve dug deeper, you know that these problems are related to the speculative execution common in modern processors, and if you dug deeper still you may have learned that underlying both problems are exploits called timing… Read More


CEO Interview: Jason Oberg of Tortuga Logic

CEO Interview: Jason Oberg of Tortuga Logic
by Bernard Murphy on 05-31-2018 at 7:00 am

I first met Jason Oberg, CEO and one of the co-founders of Tortuga Logic, several years ago when I was still at Atrenta. At that time Jason and Jonny Valamehr (also a co-founder and the COO) were looking for partners. The timing wasn’t right, but we’ve stayed in touch, for my part because their area of focus (security) is hot and likely… Read More


A Development Lifecycle Approach to Security Verification

A Development Lifecycle Approach to Security Verification
by Bernard Murphy on 02-22-2018 at 7:00 am

We have become accustomed to the idea that safety expectations can’t be narrowed down to one thing you do in design. They pervade all aspects of design from overall process through analysis, redundancies in design, fault analytics and mitigation for faults and on-board monitors for reliability among other requirements and techniques.… Read More


Software Security is Necessary but NOT Sufficient

Software Security is Necessary but NOT Sufficient
by Dr. Jason Oberg on 06-30-2016 at 12:00 pm

As the silicon designs inside the connected devices of the Internet of Things transition from specifications to tapeouts, electronics companies have come to the stark realization that software security is simply not adequate. Securing silicon is now a required, not optional, part of RTL design processes.… Read More
