    Abstract: A system, method and data storage device for encrypting data to provide at-rest data encryption of data in the data storage device. The system includes a compression engine for receiving a host data stream packet and selectively generating a compressed data packet, and an encryption engine in electronic communication with the compression engine for receiving an unencrypted data packet from the compression engine. The unencrypted data packet comprises the compressed data packet when the compression engine generates the compressed data packet. The unencrypted data packet comprises the host data packet when the compression engine does not generate the compressed data packet. The encryption engine generates an encrypted data packet having an encrypted component corresponding to the unencrypted data packet and a set of meta data indicative of one or more characteristic of the encrypted data packet.

    Abstract: A hand-held token for secure conveyance of encryption keys includes memory for holding a media key and at least one device key. Control logic reads the media key from memory, encrypts the media key based on the device key, and transmits the encrypted media key to a data storage device. The data storage device decrypts the encrypted media key using its own device key, which may have previously been downloaded from a token.

    Abstract: A multiple field nonce particularly suited for use in encryption algorithms associated with data storage has at least one field unique to each data storage device to avoid the possibility of the same nonce value being used to store more than one data string. Additional fields may be based on the number of times at least one encryption key is associated with the storage device and on a number assigned to the particular string of data.
