CITADEL is the worlds first SRAM PUF-based key provisioning system designed to keep pace with the growing demand for the generation, distribution, and protection of cryptographic keys for IoT applications. The CITADEL key provisioning system is built around a full-featured set of manufacturing and OEM managed tools. The software libraries that run on manufacturing equipment have been designed for full-speed production. The OEM management modules are ready for integration into enterprise class infrastructures.
