Managers of data centers require improvements in tape formats backup so they can keep pace with the growing demand for faster speed, lower cost, higher reliability and storage capacity of grater. The risk of having access to large volumes of data increases with growth in the tape recording format enables. The risk of data loss is greater especially when data have to be transported to other places. United Nations authorized the access and protection of critical information has emerged as a major concern for administrators of critical data. In case if you lose sensitive information from the organization, then it can lead the loss of revenue and the company also lost customers. The organization may also have to face regulatory sanctions.
So far, in order to encrypt valuable data, organizations have to bear higher costs due to the complex integration of hardware and software encryption. Hewlett-Packard has devised a solution for organizations that can help minimize the costs of encryption. HP has incorporated the technology cost-efficient encryption in LTO-4 tape format C7973W. This tape belongs to the fourth generation of Ultrium technology.
Encryption mechanism of the business class has been added to the tape automation products HP LTO4 and tape drives. HP LTO 4 tape is the fourth generation of Ultrium technology. Incorporating the latest (256-bit) Advanced Encryption Standard. Manager sends encryption keys the encryption keys for the LTO tape drive. These keys are transferred in accordance with the rules of IEEE (Institute of Electrical and Electronics Engineers), AES (Advanced Encryption Standard), GCM (Galois / Counter Mode of Operation), SCSI commands flow, IEEE SSC-3, SCSI commands SPC 4 primary and P1619.1TM/D13.

Advanced Encryption Block encryption standard was selected through a process that was considered more transparent and more open than the DES (Data Encryption Standard), its predecessor. The need encryption key for more than 56-bit led to the formation of AES. The Advanced Encryption Standard operates in the state that includes an array of bytes (4x4). Standard Advanced Encryption of each phase has four stages. The first stage is the key Add round. At this stage, the status of each byte is appended to the round key. Then a program key is used for each round key encryption key. The second stage is the sub-bytes. At this stage each of the bytes is connected with another. This change of bytes that is according to the look-up table. The third step is called the "change of ranks." At this stage, each of the ranks of the State moves cyclically. This shift is repeated in a series of steps. And finally, the fourth stage is the "Mix-Columns. At this stage, the linear transformation is performed by mixing columns the state, and in each column of 4 bytes are combined.
In addition, encryption software reduces server performance using the processor power server. The ability of the media and the backup performance degraded by the encryption software, the tape drive is not fully capable of compress the data that has been encrypted by software.
