HDD Super Bodyguard Drive Trust technology

Computers as an indispensable tool for business and personal applications have benefited many people, but with the increase in the size of the hard disk and speed, we are not comfortable with the data security of high-capacity hard disk? Hard drive data is missing, there are three reasons: one is a soft fault, usually due to hard disk write error caused by the partition table and file list confusion, usually only need to use the system's own tools or professional disk data recovery software to verify data integrity and try to fix it; Usually, depending on the severity of the situation, choose to manually screen bad sectors or send the hard disk to the data Recovery Center for recovery; the last one is the hard drive lost, the most serious loss, usually all data can not be restored, if the data on the hard disk is not important, then the loss is only money, But if the hard drive stores very important or meaningful data, the loss is very serious once the hard drive is lost, and the last loss of data for business users is the most costly.

Then has entered the 2007, we have no way to lock the hard drive, so that even if the hard drive is lost will not expose your secret or trade secrets, Seagate released Drive Trust technology will eliminate the damage caused by the loss of the hard disk, we look at Seagate Drive Trust Technology.

What is drive trust technology?

Seagate is releasing the first hard drive content protection technology that incorporates a combination of embedded hardware and software layers, which Seagate calls Drive trust, which prevents unauthorized users from viewing the data stored on the hard disk. Seagate promises that users will enjoy a high level of storage security for sensitive data, which is similar to the latest Digital rights Management (Drm,digital Rights Management) scenario (Figure 1).

Drive Trust has now been unveiled as a security-standard supplemental platform program, which was developed in collaboration with Seagate and the Computer Security Standardization Organization (tcg,trusted Computing Group), in early 2007. Seagate hopes the technology will be formally announced as a formal TCG security storage specification. This technology is based on the hardware security level, programmable basis of the full
Automated systems can also help content owners and software developers apply data security features to their related drive data development projects.

The principle of Drive trust technology

Data security is an increasingly important topic, and more and more data are being violated in the process of frequent exchange. According to the current security and replication protection mechanisms already in use, the data stored on the hard disk is almost a straightforward logical step. Drive Trust technology can enhance the convenience of management, can automatically protect all the data all the time, do not need to like the hard disk protection card to select the need to protect the partition or file, the security function does not depend on the hard disk itself, so will not affect the full performance of the hard drive, The user will be prompted to show the hard drive unlock password before the system starts, and this priority will be higher than the operating system boot.

If you don't have a password, you'll only be able to access the 2MB byte space on your hard drive, and Drive Trust technology is so powerful. If the hard drive loses the password, Seagate secretly holds a password to delete the document in the hard drive. Finally, we also notice a very useful function, that is, if you change the password, this time the hard drive data will be completely invalidated, this can maximize the security of the hard disk data, but also let those Kay qu hard drive content of the people on your hard drive.

The future of Drive Trust technology

Seagate's first hard disk product with the technology is the DB35 series, the latest security record for Seagate to be used in digital video recording to store hard disk products. By the first quarter of 2007, Seagate would have embedded Drive trust technology in its 5400-speed 2.5-inch momentus fde laptop hard drive.

The Secure Password input window provided by the hard disk, which takes precedence over the operating system boot files in the read partition (Figure 2, 3).

Summarize

At present, Drive trust technology can safely guarantee the security of data, but its use for the current widely considered sufficient security of 128-bit AES encryption, if the future of the computer run AES decryption instructions speed is greatly improved, then this encryption method is clearly not safe, Seagate upgrades the drive Trus technology only by upgrading the HDD firmware. Second, when the computer sleep state, the thief can steal data through the software or even drive Trus password, this is obviously not + difficult, and drive Trus technology can not prevent the computer sleep state after the transfer of data or even copy, so drive trust technology in the function is not perfect, After all, security needs to work together and be highly unified, such as working with Microsoft to build the highest priority command in the operating system, and so on.

Summary above, although the Drive Trust technology is not perfect in function, but at the present stage, is the best hardware to prevent data loss, and this feature in the 2007 a variety of Seagate hard drive to be applied, free to provide such a good function why not?
