It’s kind of frightening to see how quickly a skilled lock-picker can jimmy a lock and get in. But new technology makes it even simpler — apparently all you need is a good telephoto lens to break in to someone’s house — just wait till they leave their keys out on a table, snap a picture, and take it to an unethical key maker, and wha-la, a perfect replica:

“We built our key duplication software system to show people that their keys are not inherently secret,” said Stefan Savage, the computer science professor from UC San Diego’s Jacobs School of Engineering who led the student-run project. “Perhaps this was once a reasonable assumption, but advances in digital imaging and optics have made it easy to duplicate someone’s keys from a distance without them even noticing.”

Professor Savage presents this work on October 30 at ACM’s Conference on Communications and Computer Security (CCS) 2008, one of the premier academic computer security conferences.

Azulstar soon answered several RFPs and partnered up with major firms to bring Wi-Fi to Rio Rancho, N.M., Winston-Salem, N.C., Sacramento, Calif., and most notably Silicon Valley--a set of dozens of cities along with county government and private enterprise all wanting some kind of tiered Wi-Fi across 1,500 sq mi.

While EarthLink, MetroFi, and even Kite Networks (with their extensive Arizona buildout in Tempe launched a bit before any other large competiting network) seized the headlines, and later made news about their stalls, failures, and exits, Azulstar seemed quietly to sink into the sand. The Wireless Silicon Valley deal fell apart, as did Sacramento after efforts to get stakeholder and outside investment seemed to fail to materialize, and the marquee partners--Cisco, IBM, and Intel--just wouldn't step up to the plate to make the project move forward. Azulstar was the lead techology firm, but the money just didn't come. (Both California projects are moving forward with a different set of partners and expectations now.)

Rio Rancho was perhaps one of the biggest letdowns. City manager Jim Payne explained in an interview a few weeks ago, "They had a number of things that were going against them from the start, and they did make an attempt to meet the requirements of the contract." But Rio Rancho voted to not just terminate the contract after years of attempts to make the network work, but rejected a proposal from Azulstar a few weeks ago to switch over equipment on the poles. Azulstar now has to remove all its devices.

All of this might make the typical company head a bit depressed about his firm's future, and less than sanguine about the potential for wireless broadband to work at all. Not so for Tyler van Houwelingen, Azulstar's chief, and I have to admit that he convinced me that the wireless provider has a fighting chance, due to a good combination of timing, spectrum policy, and a large dollop of can-do spirit.

Their technical description of what they're doing makes a lot of sense, and if they can pull off their trial work in a production environment, they will have a set of patents and products that will likely be the model for deploying subway and train Wi-Fi in urban areas around the world. Yes, that's a big claim; but they have a unique and interesting solution.

The company told the Bee that they would start on heavily traveled underground routes first, with service available within 4 months of a contract. WiFi Rail relies on leaky coax, which is wiring that runs in the tunnel already, and they've overlaid Wi-Fi signals on in a way that simulates a very long antenna.

The Bee reports that they've raised $1.5m in financing so far with another round of $15m to $20m to close later this year. With a BART contract in hand, I can't imagine they'll have any difficulty getting funds. Captive audiences are worth the big bucks.
