Hardware Full Disk Encryption – Protects Critical "Data-at-Rest"

Product Overview

The X-Wall CO ASIC is the latest generation of the X-Wall real-time full disk encryption technology. The X-Wall CO maintains all functions of previous generation X-Wall ASIC while offering superior compatibility over various Host and Device. The X-Wall CO ensures privacy and confidentiality of data and credentials stored on the disk drives without degrading system performance. A cryptographic system-controller ASIC operating at the physical layer, the X-Wall CO performs"real-time"encryption to the entire disk drive, including boot sector and operating system, at 1.2Gbit/sec using Federal Government certified TDES algorithm. 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. CO's unique design also completely eliminates any dependency on operating systems or device drivers while functioning automatically and transparently, thereby eliminating user intervention.

Key Benefits

- Offers superior compatibility over various Host and Device
- Delivers significant performance improvement over traditional software disk encryption solutions
- Allows versatile Key Management/Authentications
- Eliminates platform dependency
- Provides rock solid security
- Minimizes Total Cost of Ownership (TCO)
- Requires no users' training

How does it work?

Below figure illustrates the physical application circuit from which the X-Wall CO chip resides between the motherboard Host IDE and the IDE hard drive. The X-Wall CO is engineered to be completely invisible and transparent to any host system and device, making it totally independent from any known Operating Systems including embedded designs. The X-Wall CO 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. To repurpose drive simply pull the Secret Key as entire disk media are encrypted with NIST certified 100% hardware TDES algorithm.

Various authentications mechanisms including Smart Card, Biometrics, TPM, Single Sign-On, USB key token, or PIN/Password can be engineered to protect the"Secret Key"required to operate the X-Wall CO. Upon authentication, the"Secret Key"will be delivered through X-Wall CO 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.
