Most of us when overclocking aim for stability. Hackers aim for instability by under-volting sensitive chips, which leads to incomplete ciphers which potentially exposes the secret key. This can even be accomplished remotely!

Torturing the Secret out of a Secure Chip
Forget about webservers, this has huge potential for things like consoles and mobile devices.

In the remake of WARGAMES RIPLY was under c02,and JOSHUA was trying to get in but couldn't so they cracked the glass to raise the temp and then they got a post screen,JOSHUA was in.
look at the article date, then ask yourself if darwininean awards is something you apsire too
ohhh april fool's
I could ask you the same thing, but with proper spelling.Originally Posted by DosDuoNo
This is proper research that has taken months. IEEE doesn't do april fools. Welcome to the academic world, where jokes are not funny and people get hurt.
April fools is for IT geeks who want to impress their other geek friends.

I did read in the news paper about a hacker who slowed a encryption chip by starving it "low vcore" and could decode info/code but that was old news.
Coming Soon
Foooled.

Getting back on topic, I read this earlier on Endgadget, article date March 9th. Not a Fools.

Foundational Falsehoods of Creationism
Turn error reporting off...There all done!
agreed....
Even if real, I guess the second page got missed by the OP.....from the second page:
Real-world Web servers—even overheated or overclocked ones—are not going to reliably kick out the calculation errors by the thousands required for an attack.
An attacker would effectively need to have physical access to a system to make this attack work, Kocher says. ”For a Web server, you don’t let in any bad guy who wants to come in and play with the power supply,” he says. ”You keep it behind locked doors for reasons that go far beyond just this kind of attack. Practical consequences for Web servers I would say are pretty slim.”
University of Massachusetts professor of computer science Kevin Fu says he doubts that the attack, which was staged in a lab with an easily manipulated crypto chip, could easily be executed by real-world hackers.
”In order for this attack to work in practice, the adversary needs to have access to...the electricity to a specific pin on a chip,” Fu says. ”There’s a big difference between a power outage of a building and controlling precise micropower fluctuations.”
I am glad I am not responsible for people's ignorance
I tried, that was as polite as I could make it. Believe me I had other words prepared but I managed to restrain myself.Welcome to XtremeSystems, where it's possible to make a point and defend your position without being an obnoxious twat.
Didn't miss it, the claim was made by the hackers and refuted by others therefore it is a theory nevertheless. Until someone succeeds it will remain a theory I guess!

I'll admit I only read the first paragraph of the article. But some hackers DO actually starve some chips for voltage to cause errors that can sometimes allow you to dump the contents of the chip's stored data. So while the article may or may not have any truth/lies in it, there is some small truth in it. If I remember correctly someone a few months ago was able to rip the firmware data from one of the game consoles that hasn't been able to be hacked in years by starving it for voltage and resetting the CPU.
Watch the language, don't now about you but that's extremely offensive where I come from.

Everyone stop being butthurt and focus on the news article.
Genuine article, not april fools, stop whining, discuss it or get out.
short version.ty hardware doesn't perform to spec when everything isn't perfect. God damn sloppy hardware developers; you damn well will not see that sort of mistake from companies like Intel and AMD
Fast computers breed slow, lazy programmers
The price of reliability is the pursuit of the utmost simplicity. It is a price which the very rich find most hard to pay.

Modern Ram, makes an old overclocker miss BH-5 and the fun it was
This applies to reverse engineering micro-controllers that are secured against a logic analyzer, not complex computer processor architectures.
