Implementing Memory Encryption To Protect Data In Use


In my blog “The Methods of Memory Encryption to Protect Data in Use,” I discussed how the XTS/XEX mode of encryption was the appropriate choice for protecting data stored in and accessed from memory, also known as, protecting data in use. As a quick recap, XTS/XEX uses two keys, one key for block encryption, and another key to process a “tweak.” The tweak ensures every block of memory i... » read more

Maximize Memory Security Of HPC SoCs With Efficient Crypto IP


Data that is created and transferred between billions of devices and the cloud is growing exponentially. More and more devices are entering the market, the cloud is expanding to the network edge and new applications are emerging. These factors are drivers for technological advances in high-performance computing (HPC), reshaping system-on-chip (SoC) designs to address the need for more accelerat... » read more

Week in Review: Auto, Security, Pervasive Computing


Automotive The European Union plans to approve sales of fully autonomous vehicles by the end of September, according to Politico. The legislative package will allow for the registration and sale of up to 1,500 vehicles per model per year in member countries. Level 4 autonomous vehicles are still in the development stage, but reducing human error in autos is a crucial part of the EU’s goal to... » read more

Security Risks Widen With Commercial Chiplets


The commercialization of chiplets is expected to increase the number and breadth of attack surfaces in electronic systems, making it harder to keep track of all the hardened IP jammed into a package and to verify its authenticity and robustness against hackers. Until now this has been largely a non-issue, because the only companies using chiplets today — AMD, Intel, and Marvell — interna... » read more

Security Highlight: Evil Never Sleeps


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


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


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


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


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
