Enlarge / A diagram of a side-channel attack on a virtual machine. Using a malicious VM running on the same hardware, scientists were able to recover a private encryption key.

Zhang et al.

Piercing a key defense found in cloud environments such as Amazon's EC2 service, scientists have devised a virtual machine that can extract private cryptographic keys stored on a separate virtual machine when it resides on the same piece of hardware.

The technique, unveiled in a research paper published by computer scientists from the University of North Carolina, the University of Wisconsin, and RSA Laboratories, took several hours to recover the private key for a 4096-bit ElGamal-generated public key using the libgcrypt v.1.5.0 cryptographic library. The attack relied on "side-channel analysis," in which attackers crack a private key by studying the electromagnetic emanations, data caches, or other manifestations of the targeted cryptographic system.

One of the chief selling points of virtual machines is their ability to run a variety of tasks on a single computer rather than relying on a separate machine to run each one. Adding to the allure, engineers have long praised the ability of virtual machines to isolate separate tasks, so one can't eavesdrop or tamper with the other. Relying on fine-grained access control mechanisms that allow each task to run in its own secure environment, virtual machines have long been considered a safer alternative for cloud services that cater to the rigorous security requirements of multiple customers.

After cutting a destructive path through the Caribbean, Hurricane Sandy caused extensive damage along the East Coast this week. Sandy made landfall in southern New Jersey and brought with it major flooding, travel disruption, structural damage, and power outages. New York City was especially hard hit. The storm system was so large ­-- nearly 1,000 miles wide at times -- it brought blizzard conditions to West Virginia and 20 foot waves to Lake Michigan. It is projected Sandy will have caused about $30 billion in damages in the United States. To date, the storm claimed more than 100 lives. -- Lloyd Young ( 57 photos total)

Millions of people from Maine to the Carolinas awoke Tuesday without power, and an eerily quiet New York City was all but closed off by car, train and air as superstorm Hurricane Sandy steamed inland, still delivering punishing wind and rain. The full extent of the damage in New Jersey, where the storm roared ashore [...]

There are two things you should know about Patrick Leger. Number one –Patrick Leger is an incredible illustrator. Number two – Patrick Leger spends his days musing away in North Carolina. But whereas the latter does a good job of feeding my fantasies of eloping to sunnier skies fact number one (the illustration stuff) is more than worthy of five minutes of your precious appreciation.

Google NC data center via Street View

Google may have taken extreme measures in the past to keep prying eyes from its data centers, but the search company’s latest endeavour has pulled back the curtain. As detailed on its official blog, Google has posted an expansive — and impressive — photo gallery of its data centers strewn across the globe. The company enlisted the help of photographer Connie Zhou to illustrate the technology, people, and places that keep the internet moving. As if that wasn’t enough, Google has mapped the inside and outside of its Lenoir, North Carolina server farm using Street View, allowing users to explore both the interior and exterior in great detail.

A short video has also been posted to accompany the experience, explaining exactly what...
