Knuckle Cryptographic Module
Google, Inc. - FIPS 140 #5474
The Knuckle Cryptographic Module is defined as a sub-chip cryptographic subsystem within a single-chip physical embodiment. The module is the primary component of a PCIe-based NVMe controller which provides AES-XTS encryption of data-at-rest and key management functionality per Trusted Computing Group (TCG) Opal specifications. The NVMe controller also includes a Google Titan chip for providing a Root of Trust (RoT) and boot security. The Module is intended for use by US Federal agencies or other markets that require FIPS 140-3 validated storage devices. The Module is intended to be used in a storage system.
