Autocrypt has introduced AutoCrypt PKI-Vehicles, a post-quantum public key infrastructure product aimed at automotive OEMs and suppliers that want to prepare connected vehicles for future quantum threats. Announced from Seoul, the new PKI solution supports ML-DSA, a digital signature algorithm recently selected by NIST as part of its post-quantum cryptography standardization process. Autocrypt describes the launch as one of the first commercial implementations of ML-DSA-enabled PKI tailored for vehicle environments.
The product is designed to issue and manage digital certificates for in-vehicle ECUs, telematics units, and vehicle-to-everything (V2X) communication components, while remaining interoperable with existing automotive PKI deployments. According to Autocrypt, AutoCrypt PKI-Vehicles can run in parallel with today’s classical cryptography, enabling OEMs to begin deploying quantum-safe certificates without fully replacing current infrastructure. The company emphasizes that this dual-stack approach is important for long-lived assets like vehicles, which may remain in operation well beyond the point at which quantum attacks become practical.
Autocrypt plans to showcase the product at CES 2026 and is pitching it as a way for carmakers to get ahead of regulatory and industry pressures around post-quantum readiness. The announcement notes that automotive cybersecurity regulations such as UNECE WP.29 and ISO/SAE 21434 already require structured approaches to cyber risk management, and that post-quantum migration is increasingly viewed as part of that risk landscape for connected vehicles and smart infrastructure.
AutoCrypt PKI-Vehicles illustrates how the concept of digital identity is expanding from users and devices to entire fleets of connected assets. Managing cryptographic agility at the scale of millions of vehicles is a non-trivial identity lifecycle challenge, and post-quantum PKI will introduce additional complexity around algorithm selection, certificate rollover, and interoperability with road-side infrastructure. OEMs and tier-one suppliers that adopt quantum-safe PKI early will still need to plan for overlaps between classical and PQC algorithms, with clear migration paths and governance to avoid introducing new attack surfaces during the transition.
