(InfoWorld) - Dell has become the latest and largest vendor to offer laptops featuring Seagate's full disk encryption hard drive, the 2.5 inch Momentus 5400 FDE.2. The drive was first announced after its extended gestation only last March, but that was inside laptops made by clone vendor ASI. Dell is to sell the high-security drives in its new Latitude D630 and D830 models from this week. TheÂ groundbreaking Momentus FDE.2Â -- for once this marketing clichÃ© is probably about right -- ranks as the first laptop hard drive integrating the technology to make it to the mass market. Although hard drive encryption is a common technology, the Momentus integrates the technology at hardware and drive firmware level, making it both transparent, extremely hard to crack, and because of built-in acceleration, faster than add-on encryption. In all other respects, from the user's point of view, the Momentus FDE.2 is a conventional hard drive which requires a master passphrase to be set for boot-up access. Dell is to sell the drive with the Embassy Trust Suite from software company Wave Systems, also promoted by Seagate during the drive's soft-launch in March. This allows IT admins to manage laptops using the drives, accessing such features as password recovery, and data backup of encrypted drives "Dell is at the forefront of notebook security because it ranks as a top concern for customers in an environment where more data is produced by an increasingly mobile work force," said Dell's Margaret Franco. "The industry-first solution we're announcing today adds to our multi-pronged approach to security that delivers an ironclad assurance of protection." Seagate and Dell hope that despite adding cost to a laptop -- not yet specified on the company website - businesses will jump at the chance of hard drive security in a way, thus far, they have not. Full disk encryption systems still have the reputation for being awkward to manage, difficult to use, and for slowing down the PC. Balanced against this will be the now-routine security scares caused by the loss of theft of laptops, containing important data that turned out as not-encrypted in any way. Seagate has produced a white paper, explaining the drive technology on its website. TechworldÂ is an InfoWorld affiliate.

(InfoWorld) - Researchers at Toshiba have developed a method that they say makes it possible -- barring a change in the laws of physics -- to absolutely secure distribution of encryption keys across a network. Their system, which was unveiled at this week's NanoTech 2007 exhibition in Tokyo, builds onÂ quantum key distribution, which has been the subject for research and development work for some time because it promises to make possible the secure distribution of encryption keys across a network. Currently encryption keys must be sent offline, typically on physical media in tamper-proof packages, to ensure their integrity. "With quantum key distribution we can guarantee unconditional security of the key," said Andrew Shields, quantum information group leader at Toshiba Research Europe. "What that means is it's secure from all advances in mathematics, engineering and computing." Using the system, each bit of an encryption key is encoded on a single photon of light. The quantum status of photons is changed once they are read, so if an eavesdropper snoops the key while it is being distributed, the action is immediately noticeable by the intended recipient and the key can be discarded as insecure and a new one sent. Thus it's possible for encryption keys to be securely distributed across a network and for Shields to make such a bold statement. Or at least that's the theory. In practice is very difficult to control a laser so that it reliably generates a single photon of light with each data pulse. The power can be turned down so that a single photon is emitted almost all the time but occasionally two or more photons are produced. That opens the possibility for an eavesdropper to read the second photon while allowing the first to continue on its way. Such an attack wouldn't be detectable. The Toshiba scientists say this can be guarded against by transmitting decoy photons. For these, the power of the laser is ratcheted down even further so that fewer photons are produced and proportionally fewer double photons. If an eavesdropper attempts to read part of the key by pulling off the second of each double photon, the receiver would get proportionally fewer decoy photons and so the eavesdropping could be detected, said Shields. The system on display at NanoTech 2007 involved encryption of a video link. Images from a camera were fed into an encryption device via Ethernet. The device was connected to a decryptor via two fiber optic cable runs of 25 kilometers each. One link was used for transmission of the key and another for transmission of the encrypted data. The new system with decoy photons also allows the data rate of the key-transmission link to be increased to 5.5Kbps. At that rate many keys can be transmitted per second thus helping to guard against cracking of the link through crypto-analysis. "We're looking at the possibility of commercializing this fairly soon," said Shields. One problem that remains with the technology is that it requires end-to-end connection to be across a single fiber optic cable. Routers and switches can't be used because that would involve measuring or in some way interrupting the photon, which would look the same as an eavesdropping attempt. Currently most quantum key distribution systems work over distances of up to about 100 kilometers. The technology could be made to work over a network or longer distances, but would require that each switch or routing point was in a location physically trusted to be secure from eavesdroppers, said Shields.
