Secure Storage with Hardware Encryption – Protects Critical “Data-at-Rest”

Product Overview

The X-Wall XO ASIC ensures privacy and confidentiality of data and credentials stored on the hard drives without degrading system performance. A cryptographic system-controller ASIC operating at the physical layer, the X-Wall XO microchip performs “real-time” encryption of the entire hard disk (including boot sector and operating system) at 1.1Gbit/sec using Federal Government certified DES and TDES algorithms. In contrast to software disk encryption solutions, no clear text including pass phrases is ever stored on the disk drive or held in machine memory. XO’s unique design also completely eliminates any dependency on operating systems or device drivers while functioning automatically and transparently, thereby eliminating user intervention.

Key Features

- Delivers significant performance improvement over traditional software disk encryption solutions
- Provides flexible Key Management Structure to accept versatile authentication mechanisms such as Smart Card, ....Biometrics, Single Sign-On, USB key token, or PIN/Password
- Eliminates platform dependency
- Minimizes Total Cost of Ownership (TCO)
- Requires no users' training

Description

The X-Wall XO chip resides between the motherboard Host IDE and the IDE hard drive. It intercepts and translates IDE commands and encrypts all data in real-time. All data written to the hard drive, including the boot sector, operating system, temp and swap files is automatically and transparently encrypted. Attempts to circumvent security by booting from a floppy disk or by removing the hard drive to be read on a different machine would prove futile since the entire content of the hard drive is encrypted.

Operation

Various authentications mechanisms including Smart Card, Biometrics, Single Sign-On, USB key token, or PIN/Password can be engineered to protect the “Secret Key” required to operate the X-Wall XO. Upon authentication, the “Secret Key” will be delivered through X-Wall XO to enable the operation of encryption and decryption. All existing key management systems maybe put to work without significant system platform change. Access to the disk drive will only be granted upon correct authentication.
