New Data Encryption System Coming to Storage Media

Hard disk and flash drive manufacturers such as Samsung, Seagate and Western Digital are turning to a technique known as full-disk encryption, developing storage media that automatically encrypts data as it is stored and decrypts it when it is read back. Requiring just a password, computers with such drives need no special security software.
 
 A new way to protect digital information promises an end to accidental leaks or loss of private information through theft, U.S. computer researchers say.
Information stored in computers is normally protected by a password stored in the computer’s operating system, such as Windows or Mac OS, but the data on the disk itself is not protected, so a savvy hacker or thief can sidestep the password protection and access the information, NewScientist.com reported.

Now hard disk and flash drive manufacturers have begun to turn to a technique known as full-disk encryption, developing storage media that automatically encrypt data as it is stored and decrypt it when it is read back.
Requiring just a password, computers with such drives need no special security software.

Within a year or two, researchers say, all hard disks will be protected using the full-disk encryption method. Such devices put the encryption process into a chip on the disk or drive. Everything on the disk is automatically encrypted and can be accessed with a conventional password only the computer user knows.

Anyone trying to access the disk without the password would have to contend with protection that rivals 128-bit or 256-bit Advanced Encryption Standard keys, which are virtually unbreakable, researchers say.
"Hardware is faster than software, more reliable and harder to hack," Simson Garfinkel at the Naval Postgraduate School in Monterey, California, says.
Samsung, Fujitsu, Seagate, Western Digital, Hitachi and other manufacturers have all said they plan to begin producing self-encrypting media.
