USB to USB crypto processor with AES 256-bit hardware encryption

The patents protected[1] X-Wall DX is a USB to USB real-time cryptographic module capable of encrypting entire USB portable drive including Blu-Ray DVD, DVD R/W, CD-R, thumb drive, disk, SSD, SD, CF, MMC, T-Flash & MS at USB2.0 wire speed with NIST/CSE certified hardware AES ECB/CBC 256-bit strength. The X-Wall DX safeguards content privacy via automatic and transparent encryption. The encryption content is invisible without presenting the right AES key. The X-Wall DX equips with complete USB2.0 protocol stacks that can be embedded onto a motherboard, a device, or acts as an independent ciphering dongle.

How does it work ?

The X-Wall DX sits between the USB host and the USB device, encrypting before the data is ritten to the storage and decrypting while the data is read. The cryptographic operation is totally transparent to users thus produces no performance loss while all data-at-rest are hardware AES 256-bit encrypted. The Enova Secure Authentication (ESA) software responsible for uthentication, is easy to use and requires no additional IT training.
