Scientists Extract RSA Key From GnuPG Using Sound of CPU
kthreadd writes "In their research paper titled RSA Key Extraction via Low-Bandwidth Acoustic Cryptanalysis, Daniel Genkin, Adi Shamir and Eran Tromer et al. present a method for extracting decryption keys from the GnuPG security suite using an interesting side-channel attack. By analysing the acoustic sound made by the CPU they were able to extract a 4096-bit RSA key in about an hour (PDF). A modern mobile phone placed next to the computer is sufficient to carry out the attack, but up to four meters have been successfully tested using specially designed microphones." -

Algorithms Can Make You Pretty
caffeinemessiah writes "The New York Times has an interesting story on a new algorithm by researchers from Tel Aviv University that modifies a facial picture of a person to conform to standards of attractiveness. Based on a digital library of pictures of people who have been judged 'attractive,' the algorithm finds the nearest match and modifies an input picture so it conforms to the 'attractive' person's proportions. The trick, however, is that the resultant pictures are still recognizable as the original person. Here's a quick link to a representative picture of the process. Note that this is a machine-learning approach to picture modification, not a characterization of beauty, and could just as easily be used to make a person less attractive." Note: As reader Trent Waddington points out, the underlying research was mentioned in an earlier story as well. -
Some Eye-Popping Research From Siggraph
jamie found links to a discriminating selection of Siggraph papers at waxy.org. Among the more captivating: automatically improving the attractiveness of faces in portraits; automatic substitution of similar faces into photographs (with potential applications such as a privacy-enhanced Google Street View); and using still photographs to enhance video of a static scene. -
The Future of Nanobiotech Predicted
Quadraginta writes "Aharon Hauptman and Yair Sharan of the Interdisciplinary Center for Technology Analysis and Forecasting (ICTAF) at Tel Aviv University recently presented the results of a survey of 139 researchers on the future of nanobiotech. The presentation itself is only available as a PDF file, but there is a brief news announcement from the ICTAF. Interestingly, Hauptman and Sharan asked for -- and got -- specific predictions from the experts of the year in which various nanotech marvels will appear. For example, the experts say we can look forward to biosensors capable of detecting a single molecule by 2015, the direct construction of artificial human organs by 2020, and the use of nanomachines inside the body for diagnosis and therapy by 2025." -

Rec.humor.funny Threatened by MasterCard
MotyaKatz writes: "The last article in the rec.humor.funny newsgroup comes from the editor (aka moderator), Brad Templeton himself. Amazingly, after two years, MasterCard decided that this joke violates their "priceless" trademark and requested its immediate removal. The reply of Mr. Templeton shows the sense of humor only the RHF editor can have!"Templeton's response was right on target. But I can't help taking a crack at it:
Getting the idea that you should protect your brands on the internet: free.
Hiring firms to search out and police such "violations": $millions.
Getting slammed with negative publicity because you're sending out cease-and-desist letters like a bunch of idiots, which makes your customers think of your stupidity whenever they see your commercial: $millions more.
Learning from your mistakes the first time you make them: priceless.
There are some experiences that money can't buy. For every other mistake you make multiple times, firing the executive responsible is fun too.

A Praise To Unix
MotyaKatz writes: "ZDnet has an article from Evan Leibovitch which he calls The Unix Phoenix. As he states, 'I come not to bury Unix, but to praise it'. He mostly deals with the aspects of Unix surviving during Linux growth." -
Nanobes - Life may be smaller than you think
kris writes "The existence of nano-sized organisms has been proposed for a number of years by geologists who refer to a range of mineralised structures in rocks as the fossil remnants of nanobacteria. Bacteria range in size from 150nm (Mycoplasmas)-50m in diameter while the proposed nanobacteria are an order of magnitude smaller with diameters reported to range from 20nm-150nm. How small can life be? See for yourself at the Nanoworld Image gallery. Can we build computers from microbes and nanobes? Or has this already happened in precambrian times? " -
