As AI evolves into autonomous Physical AI systems, from robots and vehicles to edge devices, trusted hardware security is essential for safe, connected operation. Beyond processors and algorithms, every device must authenticate, protect communications, secure AI models, and receive trusted updates, enabled by a hardware Root of Trust in the chip. With quantum computing rendering classical cryptography vulnerable, products designed today for 10–20-year lifespans must already be post-quantum ready. SEALSQ’s mission is to help device makers address this challenge by developing next-generation Post-Quantum Cryptography (PQC) secure microcontrollers and Trusted Platform Modules (TPMs) engineered to support the latest NIST-standardized quantum-proof algorithms Crystals Kyber and Dylithium, while being resistant also to traditional attacks. From a technology and certification compliance perspective, these products are designed to support the industry’s transition to quantum-safe security. Why Customers Can Deploy PQC Chips Today One of the most common questions we receive is whether customers should wait for Trusted Computing Group (TCG) and Common Criteria certification before deploying PQC-enabled secure chips. The answer is no. Security does not begin with certification. It begins with secure hardware implementing standardized post-quantum cryptography, hardware Root of Trust, certified entropy, secure key storage, secure boot, and protected firmware updates. For most commercial applications, including Physical AI, robotics, industrial automation, automotive, IoT, telecommunications, healthcare, smart infrastructure, and consumer electronics, organizations can begin integrating PQC chips today to ensure their products are protected against tomorrow’s quantum threats. SEALSQ Is Already Sampling Its Full PQC TPM As announced in March, SEALSQ is now sampling customers with its TPM185, a full Post-Quantum Cryptography Trusted Platform Module designed to meet the next generation of trusted computing requirements. The TPM185 has been engineered around the latest standardized PQC algorithms and is ready for customer evaluation and product integration, enabling OEMs and system manufacturers to begin designing quantum-resilient platforms today. Understanding the Certification Timeline The timeline for TCG and Common Criteria certification depends on the completion of the industry’s certification framework, including the finalized Protection Profile (PP) and the associated evaluation methodology. These elements are being developed through international standardization processes and have experienced delays affecting the entire TPM ecosystem. SEALSQ is an active participant in the Trusted Computing Group (TCG) Working Group responsible for developing the certification requirements and the new Protection Profile for post-quantum TPMs. This work is progressing collaboratively across the industry to ensure a consistent certification framework for all vendors. The current expectation is that the Protection Profile will be ready for approval by ANSSI, the French National Cybersecurity Agency, in December 2026. Once approved, it will establish the formal basis for Common Criteria evaluations of PQC-enabled TPMs. SEALSQ expects to be among the first wave of semiconductor manufacturers to submit its TPM185 to accredited evaluation laboratories for Common Criteria certification under this new Protection Profile. This situation is not unique to SEALSQ. Across the semiconductor industry, leading security chip manufacturers are introducing quantum-ready technologies while awaiting completion of the certification framework. No vendor can achieve full Common Criteria certification until the underlying Protection Profile and evaluation procedures have been finalized by the relevant international bodies. Importantly, Common Criteria does not create security, it independently validates security that has already been engineered into the product. The certification process provides additional assurance through extensive documentation, laboratory testing, vulnerability analysis, and formal evaluation. It is an important milestone, particularly for government, defense, and highly regulated industries, but it should not delay the adoption of quantum-safe hardware in commercial markets. “I’m genuinely excited that we’re already sampling our TPM185, the full Post-Quantum Cryptography TPM that lets customers start designing truly quantum-resilient platforms today,” said Jean-Pierre Enguent, CTO at SEALSQ. “Common Criteria certification will follow the Protection Profile’s expected ANSSI approval in December 2026, independently validating the robust security we’ve engineered from the start, so there’s no need to wait to begin adopting quantum-safe hardware.” Leading the Transition to Physical AI SEALSQ remains actively engaged with industry standards organizations, certification bodies, and ecosystem partners to ensure that its products achieve certification as soon as the framework becomes available. In parallel, the Company continues advancing its technology so customers can confidently deploy quantum-ready products today while seamlessly benefiting from future certifications as they become available. The migration to post-quantum security is a journey that will span many years. Waiting for every certification milestone before deploying secure hardware would unnecessarily delay innovation and leave connected products exposed throughout their operational lifetime. The era of Physical AI has begun. Its success will depend not only on intelligent algorithms, but also on trusted, quantum-safe silicon capable of securing every autonomous decision. Carlos Moreira, Founder and CEO of SEALSQ, commented: “Physical AI will transform every industry, but autonomous systems can only be trusted if their hardware is trusted. Our TPM185 and next-generation secure microcontrollers enable customers to begin the transition to quantum-safe security today. While the industry completes the Common Criteria framework, manufacturers can already design and deploy products with confidence, knowing they will be ready for formal certification as soon as the new Protection Profile becomes available.” About SEALSQ: SEALSQ is a leading innovator in Post-Quantum Technology hardware and software solutions.
