摘要： 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.

摘要： 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.

摘要： Systems and methods for retrieving data stored on a peripheral storage device such as a magnetic tape drive or disk drive include string searching using the peripheral storage device resources without transferring data to the requesting host computer and transferring only data blocks with matching data to the associated host computer to conserve host resources and data channel and/or network bandwidth.
