Microarchitecture Vulnerabilities: Uncovering The Root Cause Weaknesses

By Jason Oberg - 07 Mar, 2024 - Comments: 0

In early 2018, the tech industry was shocked by the discovery of hardware microarchitecture vulnerabilities that bypassed decades of work put into software and application security. Meltdown and Spectre exploited performance features in modern application processors to leak sensitive information about victim programs to an adversary. This leakage occurs through the hardware itself, meaning th... » read more

New Concepts Required For Security Verification

By Brian Bailey - 28 Aug, 2023 - Comments: 0

Verification for security requires new practices in both the development and verification flows, but tools and methodologies to enable this are rudimentary today. Flows are becoming more complex, especially when they span multiple development groups. Security is special in that it is pervasive throughout the development process, requiring both positive and negative verification. Positive ver... » read more

How Secure Are RISC-V Chips?

By Jeff Goldman - 05 Jan, 2023 - Comments: 3

When the Meltdown and Spectre vulnerabilities were first uncovered in 2018, they heralded an industry-wide shift in perspective regarding processor security. As the IBM X-Force Threat Intelligence Index put it the following year, "2018 ushered in a new era of hardware security challenges that forced enterprises and the security community to rethink the way they approach hardware security." R... » read more

Chip Backdoors: Assessing the Threat

By Jeff Goldman - 04 Aug, 2022 - Comments: 0

In 2018, Bloomberg Businessweek made an explosive claim: Chinese spies had implanted backdoors in motherboards used by some high-profile customers, including the U.S. Department of Defense. All of those customers issued strongly worded denials. Most reports of hardware backdoors have ended up in exchanges like these. There are allegations and counter-allegations about specifics. But as hardw... » read more

Verifying Side-Channel Security Pre-Silicon

By Bryon Moyer - 03 Mar, 2022 - Comments: 1

As security grows in importance, side-channel attacks pose a unique challenge because they rely on physical phenomena that aren’t always modeled for the design verification process. While everything can be hacked, the goal is to make it so difficult that an attacker concludes it isn't worth the effort. For side-channel attacks, the pre-silicon design is the best place to address any known ... » read more

Why Banks Should Be More Worried About Security

By John Koon - 03 Mar, 2022 - Comments: 1

At about 10:30 a.m. on Friday, Feb. 5, 2016, Jubail Bin-Huda, a joint director of Bangladesh Bank, and a colleague went to pick up the latest Society for Worldwide Interbank Financial Telecommunication (SWIFT) acknowledgement messages from the printer. When they got to the printer, they found nothing had been printed. They restarted the printer manually, but it still didn't work. They had no... » read more

Securing ICs With Information Flow Analysis

By Ed Sperling - 16 Feb, 2021 - Comments: 0

Following the data has new meaning when it comes to security. Alric Althoff, senior hardware security engineer at Tortuga Logic, talks about tracking the flow of data through a hardware design over time, including what happens with roots of trust, how this works with existing tools and methodologies, and what to think about when tracing potential security risks. » read more
