PS3, Linux Used to Catch Child Pornographers

[wildwell]

Why PS3s?

Lol yea. Forget stem cell research or research for cure for cancer... let's spend money and time to catch pedos.

Hell, let's forget stem cells, cancer AND pedophiles! Let's spend billions of dollars to find some buckets of water on a planet we can't possibly live on for the forseable future!

good excuse to game on the job

Why not a 8P motherboard with 6 sexacores?
Or a speciality order from IBM for their newest cell processors.

4,096 bit encryption anyone?

Put the cell CPU on a blade server? Sell it for cpu-intensive applications? Leave it to IBM: "On 13 May 2008, IBM announced the BladeCenter QS22. The QS22 introduces the PowerXCell 8i processor with five times the double-precision Floating Point performance of the QS21, and the capacity for up to 32GB of DDR2 memory on-blade."

The problem is as many have stated, the IBM version is not cost subsidized, and in fact much MUCH more expensive than the same CPU power when drawn from an array of PS3 systems, as long as you are dealing with problems that are easy to parallel (as brute force cryptanalysis certainly is.)

Nvidia 9800GT can bruteforce 4 million MD5 hashes per second, even though MD5 is comparitavely weak I'm sure it'd still hvae a fair go at it.

C3 uses Linux on the PlayStation 3 to run its cracking software.

Shouldn't that be LC3 or L0phtCrack-V3?

I also have a hard time believing 60 PS3s are a better choice than a few fast, but regular computers with a bunch of cores

"There's no controllers hooked up," Davenport said.

Isn't that because they're wireless?

+1. A network like BOINC could easily be set up to take advantage of the huge power found on the GPUs.

[citation][nom]JasonAkkerman[/nom]Wouldn't multiple modern GPU's with hundreds of cores each be a more cost effective solution to brute force cracking?Who thought a $400 game system would be a good option? You don't need the graphics abilities, the blue tooth, the blu-ray, hell even the harddrive.[/citation]
The Cell chip found on the PS3 can easily do 1 (or was it like 1.8?) TFLOPS. On the other hand, a high end Nehalem can do only about 80-120 GFLOPS. The ATI R800s can do ~2.8-3.1 TFLOPS.

By "child pornographers", I'm sure they mean:

political dissidents
tax evaders
those who plan on refusing the H1N1 vaccine
anybody who disagrees with the direction our country is going in

otherwise, they could better spend their time, money and resources spying on the clergy looking for pedo-folks

According to, "http/www.blachford.info/computer/Cell/Cell1_v2.html"


SPEs can also be chained, that is they can be set up to process data in a stream using multiple SPEs in parallel. In this mode a Cell may approach its theoretical maximum processing speed of 256 GigaFlops.

1-1.8TeraFLOPS sounds a little high for a PS3, no disrespect.

 

[climber]

Isn't there a US Government supercomputer using Opteron's as the data I/O and controller logic and the Cell Processors as the vector computational engines. I think there's a few thousand opeterons and a few tens of thousand Cell PPEs... Wasn't it Sandia National Labs or something?

 

[city_zen]

I'm pretty sure that or the cost of 60 PS3s they could have bought a Copacobana instead, which would have been a better solution.
From their website:

The average search time for a single DES key is less than a week, precisely 6.4 days

Can 60 PS3s do that in less than a week?

 

[Soul_keeper]

It's a shame you can't put linux on the newer low power PS3

The PS3's version of the Cell will not come close to 1.8 Tflops ( btw that was the numbers for the GPU on the PS3 , which no one believed)

Fact is the Cell will not come close to 256 gflops. it would be much closer to 20 gflops. The Cell is limited by the platform, which is severely hampered by the amount of ram.

Consider this "The amount of time required to break a 128-bit key is also daunting. Each of the 2^128 (340,282,366,920,938,463,463,374,607,431,768,211,456) possibilities must be checked. A device that could check a billion billion keys (1018) per second would still require about 1013 years to exhaust the key space. This is a thousand times longer than the age of the universe, which is about 13,000,000,000 (1.3×1010) years" Wiki.

So good luck, but maybe we can focus resources in to something practical, important, and ACHIEVABLE.

Just to be clear I'm talking about AES, And if you think you can use other encryption methods as a gauge think again. If a 56 bit DES can be bruteforced in 1 sec, (won't happen). Then AES-256 would take 5 x 10^52 years.

So like I said, I don't see why they want to attack the wall and not just go around it. Using PS3's to do so is even more foolish.
