SEALSQ and Lattice Collaborate to Deliver Unified TPM-FPGA Architecture for Post-Quantum Security

Post-Quantum Cryptography TPM-Enabled Secure RoT PoC Showcase at Embedded World, in Nuremberg,in March 2026

Geneva, Switzerland, February 18, 2026 - SEALSQ Corp(NASDAQ: LAES) ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, today announced its collaboration with Lattice Semiconductor (NASDAQ: LSCC) to integrate TPM-based advanced post-quantum security capabilities into select Lattice FPGA solutions. This collaboration addresses the rapidly growing need for quantum-resistant technologies in mission-critical applications for edge computing and other high-stakes environments.

"This collaboration perfectly illustrates SEALSQ's strategy of extending our leadership in post-quantum security beyond direct OEM sales," said Bernard Vian, General Manager ofSEALSQ. "We continue to deliver ready-to-deploy and custom secure chips directly to customers, while also leveraging our deep expertise in post-quantum hardware and flexible semiconductor design capabilities to empower strategic partners across the industry. Collaborating with Lattice allows us to bring ourcutting-edge, tailored PQC protection to their FPGA platforms, accelerating the secure transition to quantum-resistant systems for a broad range of high-performance applications."

"Lattice is committed to advancing security for our customers as the industry prepares for a post-quantum future. By combining SEALSQ's QS7001 and QVault TPM based post‑quantum capabilities with Lattice's long-running leadership insecure, power‑efficient FPGA platforms, we further expand our quantum-capable portfolio of solutions that give our customers a variety of ways to achieve quantum-resilience in their designs with strong assurance and performance," said Eric Sivertson, Vice President of Security Business at Lattice Semiconductor.

A Proof-of-Concept of the FPGA-TPM solution integrates a Lattice secure FPGA with SEALSQ's PQC based QS7001 and QVault TPM secure Root-of-Trust (RoT). The PoC demonstrates the technical feasibility of embedding TPM-based post-quantum cryptography directly into FPGA architectures and will serve as a foundational reference design for enhanced edge security.

By combining Lattice’s expertise in low power programmable FPGAs and recognized leadership in security with SEALSQ's specialized post-quantum capabilities, this collaboration demonstrates technical interoperability and supports broader industry efforts toward next‑generation quantum‑secure hardware.

This initiative aligns with the launch of the Year of Quantum Security 2026 (YQS2026) in Washington, D.C., where stakeholders from government, industry, and academia converged around a shared conclusion: quantum security is no longer theoretical, it is now an infrastructure and governance imperative. Both companies support industry efforts to advance post‑quantum standards recommended by organizations such as NIST.
