Security Highlight: Evil Never Sleeps
By Marc Witteman - 07 Jul, 2022 - Comments: 0

Recently, Apple introduced a useful but potentially dangerous feature to its iPhones. Most of us would assume that a phone becomes inactive when switched off by the user or due to low power. Surprisingly, newer phones continue limited functionality for several hours in low power mode or even if it is off. This includes cards in your Wallet and the Find My service. This feature caught the attent... » read more

A New Phase In The Journey To Trustworthy Electronic Products
By Andreas Kuehlmann - 07 Jul, 2022 - Comments: 0

Semiconductor chips drive our everyday lives – and our global economy – in more ways than any of us could have envisioned when Tortuga Logic was founded in 2014. And similarly, the importance of hardware security has grown dramatically beyond what anyone could have predicted at that time. This has led us to redouble our effort to help the industry develop trustworthy products in the next ph... » read more

Safeguarding A Digital Transformation Across The Entire Product Lifecycle
By Matt Walsh - 07 Jul, 2022 - Comments: 0

In 2020, the SolarWinds breach highlighted the emergence of software supply chain attacks as a very real security threat that impacted many high-profile companies. (The software supply chain includes third-party and open-source components used in a software product.) Then in late 2021, not to be outdone, the massive scope of the Log4j vulnerability emerged, impacting millions of consumer produc... » read more

Advancing The Maturity Of Your Hardware Security Program

Where are you today on the Hardware Security Maturity Model? Hardware security is a journey. LEVEL 1: Foundational Define security requirements and validate hardware security features are working with functional verification. LEVEL 2: Basic Introduce threat models and security verification requirements while also enabling hardware protection mechanisms. Ad hoc security verification beg... » read more

Risks Rise As Robotic Surgery Goes Mainstream
By John Koon - 30 Jun, 2022 - Comments: 1

As robotic-assisted surgery moves into the mainstream, so do concerns about security breaches, latency, and system performance. In the operating room, every second is critical, and technology failures or delays can be life-threatening. Robotic-assisted surgery (RAS) has around for a couple decades, but it is becoming more prevalent and significantly more complex. The technology often include... » read more

Research Bits: June 21
By Jesse Allen - 21 Jun, 2022 - Comments: 0

Side-channel protection for edge AI Researchers from the Massachusetts Institute of Technology built a chip that can defend against power side-channel attacks targeting machine learning computations in smartwatches, smartphones, and tablets. Side-channel attacks involve observing a facet of the device's operation, in this case power, to deduce secrets. “The goal of this project is to buil... » read more

Chips Can Boost Malware Immunity
By John Koon - 15 Jun, 2022 - Comments: 0

Security is becoming an increasingly important design element, fueled by increasingly sophisticated attacks, the growing use of technology in safety-critical applications, and the rising value of data nearly everywhere. Hackers can unlock automobiles, phones, and smart locks by exploiting system design soft spots. They even can hack some mobile phones through always-on circuits when they are... » read more

The Methods Of Memory Encryption To Protect Data In Use
By Rocky Zhang - 06 Jun, 2022 - Comments: 0

In my blog “The Importance of Memory Encryption for Protecting Data in Use,” I discussed the growing industry consensus on the imperative of incorporating memory encryption in computing architectures. In part two of this series, I’ll explore the cipher algorithms and modes that can be used to protect data stored in and accessed from memory, or in other words, used to protect data in use. ... » read more

Chip Substitutions Raising Security Concerns
By Ed Sperling - 02 Jun, 2022 - Comments: 0

Substituting chips is becoming more common in the electronics industry as shortages drag on, allowing systems vendors to continue selling everything from cars to manufacturing equipment and printer cartridges without waiting for a commoditized part. But substitutions aren't always an even swap, and they increase security risks in ways that may take years to show up or fully understand. So fa... » read more

Automotive Bandwidth Issues Grow As Data Skyrockets
By Ann Mutschler - 02 Jun, 2022 - Comments: 0

Bandwidth requirements for future vehicles are set to explode as the amount of data moving within vehicles, between vehicles, and between vehicles and infrastructure, continues to grow rapidly. That data will be necessary for a variety of functions, some of which are here today and many of which are still in development. On the safety side, that includes everything from early warning systems... » read more
