Quantinuum and Cybertrust Japan integrated quantum-computing-hardened private keys into a new certificate issuance and distribution platform for IoT devices. Cybertrust Japan's new authentication infrastructure for large volumes of IoT devices includes the NIST-selected post-quantum cryptography (PQC) algorithms.

IoT devices typically use certificates to authenticate their connection to other devices or networks to prove that they are trusted devices. The challenge when providing and managing certificates across these devices is complex because of the volume of devices trying to connect to networks and the need to provide fast access to data. Security measures need to be robust while also enabling real-time communications.
