What an exciting month it has been. Over the past few weeks, our team has had the privilege of presenting our technology on three different stages across two continents, engaging with chip designers, security researchers, and SoC architects from all over the world. Different audiences, different formats, different time zones, but one common thread running through every conversation: how do we build trust into silicon, and keep that trust intact in a post-quantum, AI-driven world? At Design And Reuse IP-SoC, Silicon Valley, Matthew Yu presented “Architecting a Flexible Root-of-Trust Across SoC Security Frameworks” and talked about • Different SoCs carry different stakes, from DPUs to automotive to FPGAs, each demands a security foundation tuned to its threat model • PUFrt adapts across the three major SoC security frameworks: open RoT (Caliptra), Arm PSA, and custom HSM subsystems • One trust anchor, three architectures, avoid rework At CYBERSEC 2026, Taipei, Webber Hu presented “Strategizing for the Post-Quantum Era: PQC Hardware Security Architecture” and talked about • The global PQC standardization timeline is here but PQC algorithms alone can't stop physical attacks • PUF, the chip's "innate fingerprint" born from quantum-tunneling variations, is the unclonable foundation that makes post-quantum security real in deployment • Is hiding your key under the doormat really secure? At IEEE HOST Symposium, Washington DC, Felix Hsu & MengYi Wu presented “PUF-Based Hardware Security: From Hardware Root of Trust to the AI Era” and talked about • New threat models in the chiplet era include supply chain attacks, Trojan chiplets, counterfeit parts, die-to-die man-in-the-middle • NeoPUF delivers near-ideal entropy across foundries and process nodes, NIST SP800-90B certified, with Riscure-certified anti-tampering • PUFrt has been selected as part of Armv9 RSE, powering Arm's Confidential Computing Architecture A few themes kept resurfacing no matter the audience or language: 🔐 Key storage is the silent weakest link. Every cryptographic system is only as strong as where its keys live. ⚛️ PQC and PUF solve different problems. Algorithms defend against tomorrow's quantum math, PUF defends against today's physical probes, and real security needs both of them. 🧩 Architecture-agnostic beats vendor-locked. Chip teams want a foundation they can drop into Caliptra, PSA, RSE, or their own subsystem without redesigning around it. To everyone who attended a talk, stopped by our booth, asked a sharp question, or grabbed a coffee with us — thank you. These conversations are what make it worth it. Already looking forward to the next one. #HardwareSecurity #PUF #PQC #RootOfTrust #Caliptra #ConfidentialComputing #Chiplet
