Managers of data centers must be improved in the tape backup formats that can keep up with increasing demands speed, lower cost, reliability and the possibility of increasing memory grater. Risk of access to larger amounts of data increases with the increase capacitates tape recording format. The risk of data loss is greatest, in particular, where data must be transported to other places. Not authorized access and protection of critical information has become an important and serious threat to data managers. If the confidential information of the organization is lost, it can lead to loss of revenue and the company will lose customers. The organization may also face legal sanctions.
So far to encrypt valuable data, organizations have to bear heavy costs in connection with the comprehensive integration of software and hardware encryption. Hewlett-Packard has developed solution for organizations that can help to minimize the cost of encryption. HP has included cost-effective encryption technology in the format C7973W LTO-4 tape. This tape belongs to the fourth generation of Ultrium technology.
Enterprise-class encryption mechanism was added to the HP LTO-4 tape automation and tape drives. HP LTO 4 tape belongs to the fourth generation of Ultrium technology. It contains the latest (256 bit) Advanced Encryption Standard. Encryption key manager sends keys to the LTO tape. These keys are transmitted in accordance with IEEE (Institute of Electrical and Electronics Engineers), AES (Advanced Encryption Standard) GCM (Galois / Counter Mode of operation), the stream of SCSI commands, IEEE SSC-3, SCSI SPC four basic commands and P1619.1TM/D13.

Advanced Encryption Standard block cipher was selected through a process, which was considered more transparent and open than the DES (Data Encryption Standard), which is its predecessor. The needs of the encryption keys for more than 56-bit led to the creation of AES. Advanced encryption standard works on the state, which consists of an array of bytes (4x4). Advanced encryption standard in each phase consists of four stages. The first stage is a round button Add. At this stage, every byte of state is attached to the round-key. Then key schedule is used to create each round-key encryption, key. The second stage is a sub-bytes. At this stage, each byte is on the other. This Switching bytes is performed in accordance with the look-up table. The third stage is called "shift-rows." In this phase, each country moves rows cyclically. This shift is repeated for many steps. And finally the fourth stage is the "Mix" column. At this stage, a linear transformation takes place through mixing the columns of the State in each column are connected to 4 bytes.
On the other hand, reduces the efficiency of encryption software uses the server CPU by the server. Capacity of the media and the backup is degraded by the tape drive encryption software is not able to fully compress the data, that were encrypted by the software.
