LSI Corporation is committed to delivering the highest quality and most reliable Flash Storage Processors (FSP) in the marketplace. As part of a detailed validation and quality assurance analysis of the security implementation in the SF-2000 series FSP, it was discovered that the AES-XTS engine was restricted to 128-bit encryption.
This issue affects the limited set of users who currently require 256-bit encryption. The necessary hardware and firmware updates are currently in process to enable full 256-bit encryption for those customers who need it.
“AES-128” and “AES-256” refer to encryption key lengths of 128 and 256 bits respectively; the higher the number of bits in a key, the stronger the level of encryption.
LSI believes AES 128-bit encryption meets the data encryption requirements of most customers. Customers that believe they require 256-bit encryption should contact their SSD manufacturer to obtain specific information about their SSD.
