A car built today may still run in 2045. The encryption inside it must last just as long. That is the problem SEALSQ says it will solve. The company has laid out a post-quantum automotive security roadmap. It wants to design quantum-resistant cryptography into the silicon of future vehicles. The vision is bold. The delivery is still a plan.
“Automotive customers are asking for one thing: silicon that is safe, secure and built to last,” said Jean-Luc Triouleyre, General Manager of SEALSQ ASIC Design Services.
SEALSQ’s Post-Quantum Automotive Security Roadmap
SEALSQ did not launch a product. It announced a vision and a roadmap. The Geneva-based chip firm trades on Nasdaq as LAES. It plans a full line of automotive security parts. The list runs from Trusted Platform Modules to fully custom quantum-resistant ASICs.
The building blocks have names. TPMs and secure microcontrollers sit at the simple end. Licensable HSM IP and chiplet-based security modules sit in the middle. A custom “QASIC” sits at the top. SEALSQ calls the QASIC a concept, not a catalogue item.
The capability rests on a 2025 acquisition. SEALSQ bought IC’Alps and gained close to 100 ASIC design engineers. Many carry automotive chip experience. That team now anchors the company’s custom-silicon ambition.
Carlos Moreira is SEALSQ’s chairman and chief executive. In a vehicle, he said, safety and security “can no longer be separated, and today’s cyber risks cannot be separated from tomorrow’s quantum threats.” The claim is fair. The roadmap to prove it is long.
Why Cars Are A Post-Quantum Problem
Vehicles live on the road for 15 to 20 years. Their cryptography must survive that whole span. Quantum computers threaten the math behind today’s encryption. A car sold now could face that threat mid-life.
Attackers are already preparing. They steal encrypted data today and store it. They plan to decrypt it once quantum tools arrive. Security teams call this harvest now, decrypt later. Firmware and vehicle data both sit in the crosshairs.
The standards world has moved. In August 2024, NIST finalized its first post-quantum encryption standards. Those cover key exchange and digital signatures. NIST urged administrators to start migrating at once. SEALSQ’s designs aim to carry that migration into cars.

The Insurance Blind Spot On Wheels
Here is why underwriters should read on. Cyber policies rarely price the cryptography they rely on. Quantum risk turns that blind spot into a long tail. A theft today could surface as a breach years later.
Most cyber cover is written on a claims-made basis. It pays when a claim lands, not when the act occurred. Data stolen in 2026 could be decrypted in 2033. The policy in force then may exclude the older act. The loss can fall through the gap.
Some carriers now name the risk out loud. Cowbell built quantum exposure into its Prime One policy this year. The cover treats harvest now, decrypt later as a present variable. Most of the market still calls quantum a distant worry.
Cars add their own layer. Insurers are only starting to write vehicle cyber cover. HSB, part of Munich Re, launched auto cyber insurance for fleets in February. HSB’s Eric Hendricksen called vehicle attacks “a real and growing threat.” Quantum stretches that threat across the vehicle’s whole life.
The Rules Are Already Here
Regulation is the near-term driver, not quantum. The UNECE R155 regime makes cybersecurity a type-approval condition. It now applies to new vehicles across Europe. ISO 26262 and ISO/SAE 21434 sit alongside it. Together they force security into vehicle design.
SEALSQ leans hard on these standards in its pitch. Its design flow claims compliance with all three. That matters to buyers who must prove it at vehicle level. A compromised control unit is now a safety problem, not just a data one.
The automotive cyber market is widely expected to grow alongside the rules. Connected and software-defined vehicles widen the attack surface. High-profile car cyber incidents keep the pressure on. AI-driven threats, tracked in cases like Immunefi’s research, sharpen the risk further.
What It Means For Underwriters
Treat this as a supplier signal, not a fix. SEALSQ has a roadmap, engineers and standards heritage. It does not yet have shipping automotive silicon. The announcement names no OEM customers and no ship dates.
The exposure on the road today does not change. Millions of cars already run classical encryption. They will stay on the road well into the quantum era. Their data is being harvested now, whatever chips come next.
For underwriters, two signals are worth tracking. R155 compliance is becoming a floor for insurable risk. Quantum-safe silicon, once real, could shape future terms. Until then, the blind spot stays open. A roadmap does not close it.
FAQ – Post-Quantum Automotive Security And SEALSQ
It means protecting a vehicle’s data and firmware with quantum-resistant cryptography. The goal is cover that survives future quantum attacks. SEALSQ wants to build it into vehicle silicon.
No. SEALSQ announced a vision and a roadmap. It named no carmaker customers and no ship dates. The QASIC chip is described as a concept.
Cars stay on the road for 15 to 20 years. Their encryption must last that long. Quantum computers could break today’s math mid-life.
Attackers steal encrypted data today and store it. They plan to decrypt it once quantum tools mature. The theft can stay hidden for years.
Most cyber cover is claims-made. A theft today can surface as a claim years later. That long tail is hard for insurers to price.
