SATA to SATA Real-Time Full Disk Encryption Cryptographic Processor Protecting Sensitive "Data-at-Rest" with AES 256-bit Strength
Product Overview

The X-Wall MX family ASIC (Application Specific Integrated Circuit) is the 7th generation of X-Wall Technology. It is engineered specifically to encrypt/decrypt entire SATA hard drive including boot sector and operating system in real-time performance. The cryptographic engine of the X-Wall MX is NIST (National Institute of Standards and Technology) of USA and CSE (Communications Security Establishment) of Canada certified hardware AES (Advanced Encryption Standard) algorithm.

How does it work?

X-Wall MX, an SATA to SATA cryptographic bridge chip, sits right in between host SATA and the device SATA hard drive, encrypting entire SATA drive with wire speed performance while providing up to 256-bit AES hardware strength.

X-Wall MX family comes with 3 (three) different chips. They are:
X-Wall MX-128, AES 128-bit strength;
X-Wall MX-192, AES 192-bit strength;
X-Wall MX-256, AES 256-bit strength;

System performance with X-Wall MX engaged is unaffected. X-Wall MX can be operated with SATA1.0a & 2.0 compliant disk drives with a sustained throughput of 150MB/sec. The performance-optimized AES hardware engine performs all encryption and decryption. There are no extra software components, eliminating entirely the memory and interrupt overheads.

X-Wall MX requires no device driver and is independent from and invisible to all known Operating Systems including embedded OS. As long as the drive is SATA1.0a & 2.0 compliant, X-Wall MX will work in the system. Once authenticated, its operation is completely transparent to all users. There is no complex GUI involved therefore your regular computing behavior is unchanged.

Key Management

Key Management with X-Wall MX can be versatile, which includes PIN/Password through Pre-boot authentication, TPM, Smartcard, Fingerprint, Single Sign On, or USB type external key token. One or more factor authentications are applicable through either two-wire serial interface or a built-in API (Application Programming Interface).

Key Benefits

- Offers wire speed performance at sustained 150MB/sec on all encryption strengths
- Operating System independent
- Provides iron-clad security through hardware-based NIST & CSE certified cryptographic AES engine
- Simplify engineering design for security targets

As the entire SATA hard drive is encrypted, there is no possibility of any secret being left unprotected on the drive, including password and "Secret Key." In an X-Wall MX protected system (drive), there is no simple way to read the data without the right "Secret Key." Only YOU have the right Key to unlock your data.

"The X-Wall MX technology is compatible with all system designs incorporating SATA hard drive technologies. A limited amount of sample chips will be made available for qualified customers for testing and evaluation. Make request to your Enova® Technology Sales representatives, or fill in the query."
