Parallel Algorithm Leads To Crypto Breakthrough 186

Hugh Pickens writes "Dr. Dobbs reports that a cracking algorithm using brute force methods can analyze the entire DES 56-bit keyspace with a throughput of over 280 billion keys per second, the highest-known benchmark speeds for 56-bit DES decryption and can accomplish a key recovery that would take years to perform on a PC, even with GPU acceleration, in less than three days using a single, hardware-accelerated server with a cluster of 176 FPGAs. The massively parallel algorithm iteratively decrypts fixed-size blocks of data to find keys that decrypt into ASCII numbers. Candidate keys that are found in this way can then be more thoroughly tested to determine which candidate key is correct." Update by timothy, 2010-01-29 19:05 GMT: Reader Stefan Baumgart writes to point out prior brute-force methods using reprogrammable chips, including Copacobana (PDF), have achieved even shorter cracking times for DES-56. See also this 2005 book review of Brute Force, about the EFF's distributed DES-breaking effort that succeeded in 1997 in cracking a DES-encrypted message.

Does Personalized News Lead To Ignorance? 396

blackbearnh writes "As newspapers struggle to survive and local broadcasts try to find a way to compete with cable news, more and more news outlets are banking on what people want to hear about, rather than what they need to hear. Thoughtful analysis of problems is being pushed out of the way to make room for more celebrity gossip. Electronic news guru Chris Lee thinks that as people get news increasingly tailored to their tastes, the overall knowledge of important issues is plummeting. 'I think one of the observations about how consumers are behaving in the past five years that has surprised me the most is, again, this lack of feeling responsible for knowing the news of their country and their local government of that day. I don't think it's just a technology question. I think if you asked people now versus the same age group 20 years ago, I think they'd be stunningly less informed now about boring news, and tremendously more knowledgeable about bits of news that really interest them.'"

Hidden Fees Discovered For "Free" Windows 7 Upgrade 406

An anonymous reader writes 'Thousands of recent computer purchasers who are expecting to receive free upgrades to Windows 7 when it is released on October 22 may be surprised to learn that some big computer makers are quietly tacking on hefty processing fees as high as $17 to mail out those disks to some buyers.' How about they process $0 to click a link and download a file?

How Famous OS Logos Got Started 103

Shane O'Neill writes "Ronald McDonald and the NBC Peacock may get more TV air time, but today's operating systems have cool logos, too. Google, Apple, Microsoft and the Linux crowd crafted mascots ranging from cute lizards to circles of life. In this slideshow, we look at the origins of the logos and look ahead to their future."

MI5 Website Breached By Hacker 71

Jack Spine writes "UK intelligence agency MI5 has admitted that its website security was breached by hacker group Team Elite. A member of the hacker forum posted details of the hack last week, which took advantage of a cross-site scripting vulnerability in the site's Google embedded search. MI5 admitted the breach on Wednesday, but said that the flaw had not been exploited maliciously."

Cats "Exploit" Humans By Purring 503

An anonymous reader notes a BBC report on research recently published in the journal Current Biology, indicating that cats manipulate humans by adding a baby-like cry to their purring. "Cat owners may have suspected as much, but it seems our feline friends have found a way to manipulate us humans. Researchers at the University of Sussex have discovered that cats use a 'soliciting purr' to overpower their owners and garner attention and food. Unlike regular purring, this sound incorporates a 'cry,' with a similar frequency to a human baby's. The team said cats have 'tapped into' a human bias — producing a sound that humans find very difficult to ignore."

Does Bing Have Google Running Scared? 560

suraj.sun alerts us to an anonymous-source story up at the NY Post, not what we would normally consider a leading source of tech news, claiming that Microsoft's introduction of Bing has alarmed Google. "...co-founder Sergey Brin is so rattled by the launch of Microsoft's rival search engine that he has assembled a team of top engineers to work on urgent upgrades to his Web service, The Post has learned. Brin, according to sources..., is himself leading the team of search-engine specialists in an effort to determine how Bing's crucial search algorithm differs from that used by [Google]. 'New search engines have come and gone in the past 10 years, but Bing seems to be of particular interest to Sergey,' said one insider, who spoke on the condition of anonymity. The move by Brin is unusual, as it is rare these days for the Google founders to have such hands-on involvement in day-to-day operations at the company, the source added." CNet's coverage of the rumor begins with the NY Post and adds in Search Engine Land's speculation on what the world of search would look like if Yahoo exited the field.

GM's Hummer Brand To Be Sold To a Chinese Company 429

An anonymous reader writes in to note that GM will sell its Hummer brand to Sichuan Tengzhong Heavy Industrial Machinery Co. of China, a little-known industrial firm. For now, the deal will save 3,000 jobs in the US. (The military HumVees are made by a separate company and are not involved in this deal.) "As part of the deal, some GM plants will continue to build the Hummer brand for the new owner, at least for awhile. The company said its Shreveport, La., plant will keep building Hummers for the new owner until at least 2010. ... GM said it sold 5,013 Hummers worldwide in the first quarter, down 62% from the 13,050 that it sold in the same period the prior year." AP coverage has more details on GM's planned divestitures, including the shedding of Pontiac, Saturn, and Saab.
