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

Geneva, Switzerland, Feb. 18, 2026 (GLOBE NEWSWIRE) --

Post-Quantum Cryptography TPM-Enabled Secure RoT PoC Showcase at Embedded World, in Nuremberg, in March 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 of SEALSQ. "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 our cutting-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 in secure, 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 QS7001and 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.
