UK physically unclonable function is quantum based Crypto Quantique is a London company created to licencing technology that provide end-to-end encrypted security for embedded systems. Its products include a hardware root-of-trust, which has already been licenced to a “a big semiconductor company for a high-end MCU”, according to company co-founder and CEO Shahram Mossayebi ( pictured). Mossayebi should know about security: he has an MSc in information security and a PhD in post-quantum cryptography from the University of London. The root-of-trust is a physically unclonable function (PUF) called QDID, and its other product is QuarkLink, a server-based IoT security programme that handles firmware and cryptographic key provisioning, over-the-air firmware updates, certification and key management. QDID and QuarkLink can be used together, or separately with third-party products.
