Crypto Quantique adds TRNG to quantum-secure PUF IP block
Summary
The QDID PUF is hardware silicon IP that harnesses quantum tunnelling current variations on a standard CMOS process as a source of entropy. These are consistent, device-specific outputs for a given input (challenge), making them suitable for applications that need repeatable, unique identifiers or keys tied to a specific hardware instance. The assessment of electromagnetic emissions of the IP proved that there is no correlation with either the tunnelling current variation as the source of entropy or the cryptographic secret keys generated in the semiconductor. Crypto Quantique’s CEO, Shahram Mossayebi, commented: “Side-channel attacks continue to pose a growing threat to connected devices and IoT networks. The QDID PUF and TRNG provide the ultimate protection against such risks because of the unique characteristics of gate tunnelling as a source of entropy.”
