SEALSQ Corp announced a strategic partnership with Trusted Semiconductor Solutions (TSS) to co-develop “Made in US” secure semiconductor solutions featuring post-quantum cryptography for US defense and government agencies. The collaboration pairs TSS’s Category 1A Trusted accreditation and defense ecosystem relationships with SEALSQ’s post-quantum semiconductor technology, certifications, and personalization expertise.

The roadmap spans three phases: a short‑term PQC-enabled solution combining SEALSQ’s QS7001 secure element with TSS platforms; mid‑term co-development of US‑made PQC‑embedded ICs targeting FIPS 140-3, Common Criteria, and Agency certifications; and long‑term development of next‑generation secure architectures, including chiplet‑based hardware security modules integrated with advanced secure elements or enclaves using pre‑certified IP.

The report is incorporated by reference into the company’s Form F‑3 and Form S‑8 registration statements.

Insights

Partnership targets US defense with PQC chips; certification is key.

SEALSQ and TSS align complementary strengths: TSS brings Category 1A Trusted status and defense relationships, while SEALSQ contributes post‑quantum cryptography (PQC) silicon, certifications, and personalization. The near‑term plan integrates SEALSQ’s QS7001 secure element with TSS platforms to establish a deployable baseline.

Mid‑term aims include US‑made PQC‑embedded ICs targeting FIPS 140-3, Common Criteria, and Agency certifications—regulatory milestones that often govern adoption in federal programs. Long‑term, chiplet‑based HSM architectures with secure elements or enclaves indicate a pathway to higher assurance products.

Commercial traction will depend on achieving the stated certifications and aligning with defense procurement needs. Subsequent filings may provide specifics on timelines, products, or any awarded programs.
