Securing Terabit Ethernet For AI: Where MACsec, IPsec, And UET TSS Each Fit (And Why You Need More Than One)
By Vincent van der Leest - 04 Jun, 2026 - Comments: 0

As AI and HPC systems scale, the network has become both a critical enabler of performance and a rapidly expanding attack surface. The shift from rack-scale compute to cluster- and data center-scale AI infrastructure means that data is no longer confined to a single chip, board, or even system. Instead, it moves continuously across hundreds, or thousands, of endpoints, often at aggregate bandwi... » read more

Securing Chiplet-Based Platforms: Distributed Trust With Centralized Authority
By Berardino Carnevale - 07 May, 2026 - Comments: 0

In previous blogs, From Monolithic SoCs to Chiplets: A New Hardware Security Paradigm, and Developing a Security Framework for Chiplet-based Systems, we discussed why chiplets change the game from a security perspective, and why security must be addressed at a platform-level in a chiplet-based system. In a monolithic device, trust is often implicitly bounded by the die itself: sensitive asse... » read more

Developing A Security Framework For Chiplet-Based Systems
By Berardino Carnevale - 02 Apr, 2026 - Comments: 0

In a previous blog, From Monolithic SoCs to Chiplets: A New Hardware Security Paradigm, we discussed why chiplets change the game from a security perspective, and why security must be addressed at a platform-level in a chiplet-based system. In a monolithic SoC, device identity is often anchored in a single root of trust that owns key material and policy. In a chiplet platform, every security... » read more

Ultra Ethernet Security (UET‑TSS) Tailored For AI And HPC
By Maxim Demchenko - 05 Mar, 2026 - Comments: 0

As AI and high‑performance computing (HPC) systems scale from racks to entire data centers, the network has become both a performance enabler and a growing attack surface. Modern AI fabrics interconnect thousands of GPUs and CPUs, move massive volumes of sensitive model data, and increasingly rely on direct memory access rather than host‑mediated communication. These trends exposed a fundam... » read more

From Monolithic SoCs To Chiplets: A New Hardware Security Paradigm
By Berardino Carnevale - 05 Feb, 2026 - Comments: 0

Chiplet architectures are quickly becoming the dominant approach for building scalable, heterogeneous SoCs. By disaggregating a monolithic die into multiple interoperable chiplets, silicon designers gain flexibility in process node choices, reuse of proven functions, and faster time-to-market. At the same time, disaggregation breaks one of the most fundamental assumptions in traditional SoC sec... » read more

Navigating FIPS 140-3
By Berardino Carnevale - 08 Jan, 2026 - Comments: 0

FIPS 140‑3 is a U.S. federal standard. Validations are issued under the Cryptographic Module Validation Program (CMVP), jointly managed by the National Institute of Standards (NIST) and the Canadian Center for Cyber Security (CCCS). These validations are accepted by both U.S. and Canadian federal agencies. The standard imposes strict requirements on security boundaries, operational environmen... » read more

TEE.fail: When Your Security System Leaves the Window Open
By Scott Best - 04 Dec, 2025 - Comments: 0

Let’s talk about a cybersecurity attack that’s been making waves: TEE.fail. TEE stands for Trusted Execution Environment. Sounds reassuring, right? But here’s the kicker: exactly what a TEE is, and what it’s supposed to guarantee, is surprisingly unclear. TEEs have been around for about a decade, but as with many things in security, the rules are more like guidelines. You might think, â... » read more

Confidential Computing To Secure AI Workloads
By Ajay Kapoor - 06 Nov, 2025 - Comments: 0

Artificial Intelligence (AI), data analytics, and high-performance computing (HPC) are transforming industries such as healthcare, finance, and manufacturing. These workloads rely on distributed systems managing massive datasets with high reliability. As computational demand grows, so does the need for end-to-end data protection. Traditional security addresses Data at Rest (DAR) and Data in ... » read more

Why Anti-Tamper Sensors Matter: Delivering A Comprehensive Security Solution
By Raj Uppala - 09 Oct, 2025 - Comments: 0

If your device processes valuable data, controls a critical function, or connects to a wider network, it’s a target. Attackers don’t just try to break software; they increasingly physically tamper with hardware: probing, fault injecting, or opening enclosures to bypass protections and extract secrets. The consequences range from IP theft and fraud to orchestrated downtime across fleets ... » read more

Network Security For AI/HPC: From MACsec/IPsec Towards Ultra Ethernet
By Maxim Demchenko - 04 Sep, 2025 - Comments: 0

The modern world is increasingly a digital one that encompasses the realm of electronic devices, the internet, and online platforms. This world is constantly evolving, driven by technological advancements and shaped by how humans interact with digital technologies. The key element of a digital world is information that needs to be collected, stored and processed in vast quantities. For many ... » read more
