  • Patent number: 8248723
    Abstract: Systems and methods for managing errors on a magnetic tape having a plurality of partitions accessed by a tape drive having an associated tape drive processor in communication with a host computer having an associated host processor include receiving mapping information from the host computer that designates at least first and second logically adjacent partitions for reading/writing consecutive data, receiving a read/write request to transfer the consecutive data for the first and second partitions, detecting a data error when attempting to read/write the data for the second partition and communicating a corresponding data error message to the host computer, and receiving modified mapping information from the host computer that designates a third partition as logically adjacent to the first partition for reading/writing the consecutive data.

  • Patent number: 8050407
    Abstract: A method of protecting a media key including obtaining the media key, obtaining an auxiliary key, calculating a split key using the media key and the auxiliary key, encrypting the split key using a wrap key to generate an encrypted split key, assembling the encrypted split key and a communication key to obtain a data bundle, and sending the data bundle to a token, where the media key is extracted from the data bundle on the token to protect data on a storage device.

  • Patent number: 7971062
    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.

  • Patent number: 7814316
    Abstract: A data encryption system with encryption integrity verification includes an encryption engine configured to receive an unencrypted data packet and generate an encrypted data packet based at least in part on the unencrypted data packet. The system also includes a decryption engine in electronic communication with the encryption engine, the decryption engine configured to receive the encrypted data packet and generate a decrypted data packet based at least in part on the encrypted data packet. The system further includes a comparator in electronic communication with the encryption engine and the decryption engine, the comparator configured to receive the unencrypted and decrypted data packets, determine whether the unencrypted and decrypted data packets are identical, and present the encrypted data packet as an output when the unencrypted and decrypted data packets are identical.

  • Patent number: 7797751
    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.

  • Patent number: 7706538
    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.
