In the world of high-capacity storage, protecting the physical media is the last line of defense. The IPC-BL120A-ZM stands as the industry's "Commander" of secure data-at-rest, utilizing the AES-XTS (XEX Tweakable Block Cipher with Ciphertext Stealing) mode. Unlike standard AES modes, XTS is specifically designed for block storage, using a "tweak" based on the logical block address (LBA) to ensure that the same data stored in different locations results in unique ciphertext.
This core allows engineers to implement FIPS-compliant, hardware-based encryption that is fully transparent to the host. It is specifically engineered to handle the unique requirements of sector-based storage—including the ability to handle data units that are not a multiple of the block size—ensuring that every byte of a drive is secured without the overhead of software-level encryption.
