SEALSQ Unveils Its Vision of Embedded Security and Post-Quantum Cryptography as Foundational Pillars of Physical AI

Building on the experience of more than 1.75 billion secure semiconductor devices

already deployed worldwide

Geneva,Switzerland, February 12, 2026 -- SEALSQ Corp (NASDAQ: LAES) (“SEALSQ” orthe “Company”), a global leader in semiconductors, PKI, and post-quantumcryptographic (PQC) hardware and software solutions, today unveiled itsstrategic vision of embedded security and post-quantum cryptography asfoundational pillars of Physical Artificial Intelligence (“Physical AI”).Building on the experience of more than 1.75 billion secure semiconductordevices already deployed worldwide, SEALSQ is seeking to position itstechnology as a trusted infrastructure layer enabling autonomous machines tosafely perceive, reason, interact with, and transact in the real world,securely and resiliently for decades to come.

From Connected Devices to Trusted PhysicalAI—Quantum-Resilient by Design

While traditional connected systems have relied on rigid automationand untrusted data inputs, Physical AI represents a paradigm shift: machinescapable of understanding spatial relationships, physical behavior, andenvironmental dynamics through multimodal sensing (vision, motion, audio, andenvironmental data). For such systems to scale safely, identity, trust, anddata integrity must be embedded in hardware, and must be resilient to futurequantum cyber threats.

SEALSQ’s unique position lies in the expertise gained from itslarge installed base of cryptographically authenticated, hardware-rooteddevices anchored in a secure Root of Trust architecture, now evolving towardPQC readiness. This provides the essential, future-proof foundation forPhysical AI systems to operate securely and autonomously at the edge.

Transforming Secure Chips into PQC-Enabled TrustedPhysical Nodes

SEALSQ is planning to extend its portfolio of securemicrocontrollers, TPMs (including next-generation PQC-enabled TPMs), andhardware security modules into trusted sensing and decision nodes. SEALSQ’svision is that next-generation secure system architectures will be built aroundembedded secure chips and chiplet-based Hardware Security Modules (CHSMs),tightly integrated with pre-certified secure enclaves and security IP blocksdesigned for seamless integration into complex system-on-chip platforms. Thesesolutions would be designed to cryptographically sign, verify, and protectreal-world data at the source using both classical and post-quantum algorithms,ensuring authenticity and integrity from capture to processing across the fulllifecycle of AI systems.

Introducing SEALCOIN.AI: The Transactional Layer

As Physical AI evolves from perception and reasoning to autonomousaction and machine-to-machine collaboration, SEALCOIN.AI aims to introduce asecure, AI-native transactional and orchestration layer that allows autonomoussystems to exchange value, services, and decisions in a verifiable andauditable manner. SEALCOIN, which focuses ondecentralized physical internet with DePIN technology and house the developmentof the SEALCOIN platform, is a subsidiary of SEALSQ’s parent company, WISeKeyInternational Holding Ltd (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY), a leadingglobal cybersecurity, blockchain, and IoT company. Built on post-quantum cryptographicfoundations and anchored in hardware Root of Trust, SEALCOIN.AI plans to enabletrusted AI-to-AI interactions, automated service execution, and secure economicincentives between machines operating in the physical world—without relying oncentralized intermediaries.

Security, Accountability, and Long-Term Sovereignty

By embedding PQC directly into hardware, SEALSQ aims to ensure thehighest level of security and long-term protection of data, identities, andtransactions against future quantum computers. Hardware-anchored identity planto ensure that every device, decision, and transaction remains verifiable,accountable, and protected against hijacking, spoofed commands, or maliciouseconomic manipulation.

This is critical for safety- and sovereignty-sensitive environmentssuch as collaborative robotics, autonomous mobility, defense systems, smartfactories, healthcare robotics, intelligent infrastructure, and sovereign AIplatforms.

Unlike software-only approaches, SEALSQ is planning to embed bothclassical and NIST-approved post-quantum cryptography directly into silicon,ensuring long-term resilience against emerging quantum-enabled cyber threats.

A Global Quantum-Resilient Root of Trust

At the core of SEALSQ’s vision is the WISeKey Root of Trust,already deployed in more than six billion devices worldwide, providing secureidentity, zero-trust authentication, and encrypted communications acrossheterogeneous ecosystems.

Carlos Moreira, CEO of SEALSQ, said: “Combined with SEALSQ’sexpanding portfolio of PQC-enabled semiconductors, including secure elements,TPMs, and next-generation secure ASICs and QASIC, and the SEALCOIN.AItransactional layer, this infrastructure forms what we describe as a‘quantum-resilient cryptographic nervous system for Physical AI’ connectingmachines, environments, and humans through secure intelligence, trustedautonomy, and programmable digital trust.”

Enabling the Next Generation of Trusted,Quantum-Resilient Autonomous Systems

As Physical AI transforms industries, from robotics and mobility toindustrial automation, critical infrastructure, smart environments, andhealthcare, SEALSQ’s scale, security-first architecture, and post-quantumleadership position the Company as a foundational enabler of autonomous systemsthat can safely operate, collaborate, and transact in the physical world overthe long term.

By extending trust from the digital domain into the physical andeconomic realms, and securing it against future quantum threats—SEALSQ ishelping ensure that the next generation of AI remains secure, accountable,sovereign, and aligned with human safety and societal needs.
