DAC 2019: Day 1
By Brian Bailey - 04 Jun, 2019 - Comments: 2

The last time that DAC was in Las Vegas was 2001. Much has changed since then. The first day kicked off with the usual ceremonies and then two short keynotes. A change from previous years is that keynotes are now on the show floor. This is presumably to ensure that once the keynotes are over, everyone sees the vendor booths. During the commencement session, it was also announced that all cof... » read more

Meltdown, Spectre And Foreshadow

Ben Levine, senior director of product management for Rambus’ Security Division, talks with Semiconductor Engineering about hardware-specific attacks, why they are so dangerous, and how they work. » read more

Cyber Attacks Against Vehicles On The Rise
By Aileen Ryan - 03 Jun, 2019 - Comments: 0

Who is worried about automotive security and safety? I, for one, most definitely am! I’ve written previously about how tackling this problem makes good business sense. But the more immersed I become in this topic, the more I feel personally concerned about the implications of this, and the snail’s-pace at which the market is responding to it. I’ve just read an Upstream Security repo... » read more

Intellectual Property: Trust… But Verify
By John Hallman - 30 May, 2019 - Comments: 0

For those around the microelectronic component industry for many years, we have seen quite a transformation of capability, sourcing of the supply chain, and now threats to these devices that drive the technology in our world today. These integrated circuits (ICs), once so simple as a few transistors, have continued to follow Moore’s Law and are now made up of tens of billions of transistor... » read more

Power/Performance Bits: May 21
By Jesse Allen - 21 May, 2019 - Comments: 0

More speculative vulnerabilities Security researchers at the Graz University of Technology, KU Leuven, Cyberus Technology, and Worcester Polytechnic Institute point to two new speculative execution vulnerabilities related to Meltdown and Spectre. The first, which they dubbed ZombieLoad, uses a similar approach to Meltdown. After preparing tasks in parallel, the processor needs to discard th... » read more

In-Chip Monitoring Becoming Essential Below 10nm
By Ann Mutschler - 20 May, 2019 - Comments: 0

Rising systemic complexity and more potential interactions in heterogeneous designs is making it much more difficult to ensure a chip, or even a block within a chip, will functioning properly without actually monitoring that behavior in real-time. Continuous and sporadic monitoring have been creeping into designs for the past couple of decades. But it hasn’t always been clear how effective... » read more

Can The Hardware Supply Chain Remain Secure?
By Andy Patrizio - 15 May, 2019 - Comments: 2

Malware in computers has been a reality since the 1990s, but lately the focus has shifted to hardware. So far, the semiconductor industry has been lucky because well-publicized threats were either limited or unproven. But sooner or later, luck runs out. Last year saw two significant incidents that shook people’s faith in the integrity of hardware security. The first was the Meltdown/Spectr... » read more

Multiple Roots Of Trust And Isolation: Key Roles For Absolute Security
By Ben Levine - 13 May, 2019 - Comments: 0

Today, there are many different security processors available to the SoC designer. A majority have a commonality, and that is they are based on the same architecture. You can call it a two-domain architecture. One is non-secure; the other is secure with a single bit dividing the secure from the non-secure. What’s more, different applications from different entities may be running in that o... » read more

FIAs Pose Tricky Security Attacks
By Bart Stevens - 02 May, 2019 - Comments: 0

Voltage and clock glitching are terms crowding into the emerging lexicon of chip security attacks. These are two popular methods adversaries use that can be categorized under the umbrella of fault injection attacks (FIAs). Micro-architectural vulnerabilities like Meltdown, Spectre, Foreshadow and Spoiler have been in the limelight for months. But now, FIAs are getting more attention as the indu... » read more

Creating A Roadmap For Hardware Security
By Kevin Fogarty and Ed Sperling - 02 May, 2019 - Comments: 0

The U.S. Department of Defense and private industry consortiums are developing comprehensive and cohesive cybersecurity plans that will serve as blueprints for military, industrial and commercial systems. What is particularly noteworthy in all of these efforts is the focus on semiconductors. While software can be patched, vulnerabilities such as Spectre, Meltdown and Foreshadow need to be de... » read more
