Enova Technology claims that its ninth generation X-Wall DX processor is the first true, real-time hardware encryption processor for USB mass storage class devices. The hardware, full disk encryption processor encrypts all USB mass storage class (MSC) devices at USB2.0 wire speed with NIST (National Institute of Standards and Technology) and CSE (Communication Security Establishment) -certified hardware AES ECB and CBC mode of operation up to 256bit. Data-at-rest including master boot record (MBR) and boot sectors are hardware-AES encrypted. The processor can be embedded onto a motherboard USB host controller, a device USB controller, or used as an independent adaptor. It transparently encrypts all USB storage devices and does not take up a specific USB port. It splits storage into public and cipher disk, of which cipher disk partition is invisible and inaccessible without authentication.
