Abstract
An electronic encryption endpoint device includes a management interface, a storage device interface and a controller. The management interface is capable of operating as a control interface (e.g., connecting to an array controller). The storage device interface is arranged to communicate with a set of storage devices. The controller is arranged to (i) receive a key encryption key through the management interface, (ii) decrypt a portion of a key table entry of a key table using the key encryption key to extract a data encryption key from the portion of the key table entry, the data encryption key being initially encrypted within the portion of the key table entry prior to decrypting the portion of the key table entry, and (iii) encrypt data using the data encryption key and store the encrypted data in the set of storage devices through the storage device interface.
