Best graphics cards

Friday, May 22nd, 2009

We wrote about Cost-effective video cards recently, but what about better ones, if the prise does not really matter? Just read Best Of The Best: High-End Graphics Card Roundup at Tom’s Hardware. Large. Expensive. Power-consuming. But really fast — so best choice if you deal with GPU acceleration.

Btw, don’t forget to get a good coller for your new card — like this one.

NVIDIA GT300

According to The Inquirer, Nvidia GT300 promised in October. Should be a good video card for GPU-accelerated password cracking :).

New ATI Radeon card

Thursday, April 16th, 2009

The only our product that works with ATI cards (right now) is Wireless Security Auditor, but interesting news anyway: ATI Radeon HD 4770 Info Leaked. I’ll second the editor’s opinion that it will make a good competition to NVIDIA’a 9800GT (of course, supported by EWSA, too).

Even more news from AMD/ATI: AMD Athlon X2 7850 & Phenom II X4 955 are coming. Though according to our tests (e.g. with Advanced Office Password Breaker that supoorts up to 32 processors/cores; btw, it has been updated today), multi-core AMD chips are still slower than Intel ones.

Nvidia Quadro FX 4800

Wednesday, April 15th, 2009

You should be aware that Distributed Password Recovery and Wireless Security Auditor work not only with NVIDIA GeForce cards and Tesla supercomputers (in terms of GPU acceleration), but with professional Quadro cards, too. We never compared the performance of GeForce and Quadro, though. Curious? Then read the Nvidia Quadro FX 4800: Workstation Graphics At Its Finest? article published at Tom’s Hardware today.

Technically, Quadro FX 4800 is very similar to GeForce GTX 280. But have a look at the Performance Comparison. On some tests, Quadro is up to 10 times faster than GeForce. Yes, almost the same GPU. Yes, same version of drivers. Amazing. Just note that the retail price on FX 4800 is in $1600-$2000 range. But if it can do password cracking at much higher rate than GeForce (again, we never tried it, sorry), it looks like a good investment.

User Authentication Through Desktop Scanner

Friday, April 3rd, 2009

Actually this has nothing to do with IT security, though the technique thought of by sharp guys from Princeton seems extraordinary. The research team made their way to identify fingerprints with help of a regular scanner:

This paper presents a novel technique for authenticating physical documents based on random, naturally occurring imperfections in paper texture. We introduce a new method for measuring the three-dimensional surface of a page using only a commodity scanner and without modifying the document in any way. From this physical feature, we generate a concise fingerprint that uniquely identifies the document. Our technique is secure against counterfeiting and robust to harsh handling; it can be used even before any content is printed on a page. It has a wide range of applications, including detecting forged currency and tickets, authenticating passports, and halting counterfeit goods. Document identification could also be applied maliciously to de-anonymize printed surveys and to compromise the secrecy of paper ballots.

Curious pictures publicized by Ed Felton in his blog. It is always challenging to give another life to common things we are surrounded by, similarly we suggested an alternative implementation of video cards and successfully use this technology to speed up password recovery. Inventive minds!
