The technique leverages the parallel processing power of Nvidia’s latest graphics cards to speed up the “password recovery” process by 10,000 per cent. Global Security Systems (GSS) has advised enterprises to deploy VPNs for safeguarding their WiFi networks.
We, too, can only advise you to secure your office WiFi network using VPN encryption before professional industrial sleuths start waging brute forcing blitzkriegs using ordinary graphics cards.
In what may be the biggest thing to happen to cryptography in a very long time, the world’s first computer network built with working quantum encryption technology has been demonstrated in Vienna. The network connects six locations with a total 200 km of fiber optic cable and the encryption system is said to be completely unbreakable, according to the BBC.
The network transmits a stream of millions of individual photons a second through the cable, and can detect if anyone has attempted to listen in on the stream.
Gilles Brassard, of Montreal University explained to the BBC how the system can be unbreakable: “All quantum security schemes are based on the Heisenberg Uncertainty Principle, on the fact that you cannot measure quantum information without disturbing it. Because of that, one can have a communications channel between two users on which it’s impossible to eavesdrop without creating a disturbance. An eavesdropper would create a mark on it.”
If an intrusion is detected, the data transfer is immediately rerouted through different nodes.
Pretty cool, huh? Let us know what you think of this new technology after the break.
Last week we updated our Budget Badass to reflect the current price drops and made some improvements in hardware. This week we are shifting our focus to the power user. Shifting our focus also means shifting our cost up, but a higher budget means better hardware and faster performance. We've made a couple of adjustments to the video card and CPU as well as adding a second hard drive while taking your suggestions into consideration. While the final cost of this build exceeds a little past the $2500 mark, we believe the extra performance gain is well worth it. Keep in mind this is a Power User's PC, where our main focus is on utilizing the power of the processor through multitasking and multimedia programs. Read on to see our new setup for this Power User beast.
The largest and second largest PC manufacturers in the world, HP and Dell respectively, haven’t taken an instant liking to WiMax it seems. The launch of the first commercial WiMax network in Baltimore, earlier this month, inspired OEMs Acer, Aspire, Lenovo and Toshiba to launch WiMax-enabled notebooks. However, Dell and HP did not rush to take advantage of the launch.
Moving to the largest PC supplier HP, even though the company is testing WiMax it has no immediate plans of offering support for the technology in its notebooks. It has asked its customers to explore the option of purchasing WiMax enabled PC card, USB dongle or ExpressCard, if they are keen on using WiMax. Dell and HP want to wait until WiMax becomes available in other major cities.
Many of the modern soldiers are currently saddled with battery packs that can weigh upto 20 pounds. The batteries, of course, are used to power the wide gamut of equipment that a modern soldier carries with him. However, the soldiers can now heave a sigh of relief as a wearable power system is soon going to replace the heavy batteries.
The team of America’s DuPont and Germany’s SFC Smart Fuel CellSFC Smart Fuel Cell has won the $1 million Wearable Power Prize organized by the Pentagon with its M-25 fuel cell. The M-25 weighs only 3.71 kilograms and can provide 20 watts of average power for 96 hours. The wearable system includes a fuel cell and a battery. The army has already begun using the system, though in a limited way.
Wi-Fi is fast emerging as the most popular technology for wireless communication between disparate gadgets, but security remains a major concern. However, researchers at Boston University’s College of Engineering are working on an alternative way of connecting devices that will be innately more secure than Wi-Fi.
Moreover, an LED-based communication technology will enjoy a distinct security advantage. It will be more secure compared to Wi-Fi due to the inability of light to penetrate through opaque surfaces like walls.
“Imagine if your computer, iPhone, TV, radio and thermostat could all communicate with you when you walked in a room just by flipping the wall light switch and without the usual cluster of wires,” said an ebullient Thomas Little, a BU engineering professor, about the idea. Soon, our networks will quite literally “light up”.
Just as we nerds have overhyped some technologies, we've also overlooked some even better alternatives. PC World has put on its thinking cap and posted its picks for the ten most overrated technology products and services - and alternatives that deserve a closer look.
So, How Would You Rate These Contenders?
Ultra-portable laptops versus mini-laptops
Microsoft Zune versus Apple iPod Touch
Windows XP versus Windows Vista
To discover which ones get the overrated razz, and which ones deserve some unexpected love, join us after the break.
Asus has recently admitted that some of their Eee Box desktop PC’s have shipped with a virus. While they’ve claimed that they’ve only sent boxes with viruses to Japan, it can be confirmed that other territories have received units as well.
As stated by an email sent out by Asus, the Eee Box’s 80GB hard drive has the “recycled.exe” virus files hidden in the drive’s D: partition. Once the drive is opened, the virus activates and infects the C: drive, as well as any removable drives connected to the system. Symantec states that the malware is likely to be a W32/Usbalex worm, which creates an “autorun.inf” file to trigger “recycled.exe” from D:.
With any luck, Asus will have this under control before they send out their next shipments. Until then though, be sure to look out for any of these new boxes shipping to a desk near you, they could be waiting to take all of your precious information.
E-waste is a global concern that is being deliberated upon by many researchers, legislators, activists and jurists globally. It seems all these people – at least in the U.S. – have more to think about, as it has come to light that e-waste is piling along the U.S. coastline. The large number of ships that sink around the U.S. don’t drown alone, but they carry computers that leach hazardous chemicals with them. The number of sunken vessels around the U.S. coastline is estimated to be around 10,000.
At this month’s Professional Developer Conference Microsoft will be handing out the software development kit for their Surface tabletop computer. In an announcement made on the PDC’s site, Robert Levy sates that attendees will be able to “learn how you can become a part of the expanding partner ecosystem for Microsoft Surface and leverage your existing investments in WPF (Windows Presentation Foundation) and Visual Studio to build engaging end user applications. Attendees will receive access to the Microsoft Surface SDK.”
This announcement comes as a sigh of relief to developers, who have been promised the SDK for some time now. The only known companies with access to the SDK are AT&T and Starwood hotels, whose projects are unknown. Microsoft has also been stating that the multitouch interface will be part of Windows 7, but is yet to detail how.
Let’s just hope that Chris Taylor and his boys get started on their version of Supreme Commander for the Surface ASAP!
