Addressing Quantum Computing Threats With SRAM PUFs
By Roel Maes - 06 Jun, 2024 - Comments: 0

You’ve probably been hearing a lot lately about the quantum-computing threat to cryptography. If so, you probably also have a lot of questions about what this “quantum threat” is and how it will impact your cryptographic solutions. Let’s take a look at some of the most common questions about quantum computing and its impact on cryptography. What is a quantum computer? A quantum comput... » read more

SRAM Security Concerns Grow
By Karen Heyman - 09 May, 2024 - Comments: 0

SRAM security concerns are intensifying as a combination of new and existing techniques allow hackers to tap into data for longer periods of time after a device is powered down. This is particularly alarming as the leading edge of design shifts from planar SoCs to heterogeneous systems in package, such as those used in AI or edge processing, where chiplets frequently have their own memory hi... » read more

Plugging Gaps In The IC Supply Chain
By Anne Meixner - 09 Jan, 2024 - Comments: 0

Multiple touch points in manufacturing and packaging are exposing gaps in the data used to track different components, making it difficult to identify the source of issues that can affect yield and reliability, and opening the door to counterfeit or sub-standard parts. This involves more than just assigning a simple identifying code to a chip. At different points in a device's lifecycle, new... » read more

Hiding Security Keys Using ReRAM PUFs
By Katherine Derbyshire - 21 Apr, 2022 - Comments: 2

Resistive RAM and physically unclonable functions (PUFs) have been gaining traction for completely different reasons, but when combined they create an extremely secure and inexpensive way of storing authentication keys. As security concerns shift from purely software to a combination of hardware and software, chipmakers and systems companies have been scrambling to figure out how to prevent ... » read more

Making PUFs Even More Secure
By Bryon Moyer - 06 Jan, 2022 - Comments: 0

As security has become a must-have in most systems, hardware roots of trust (HRoTs) have started appearing in many chips. Critical to an HRoT is the ability to authenticate and to create keys – ideally from a reliable source that is unviewable and immutable. “We see hardware roots of trust deployed in two use models — providing a foundation to securely start a system, and enabling a se... » read more
