+ - SPAM: Researchers find way to zap RSA algorithm 2

Submitted by alphadogg
alphadogg (971356) writes "Three University of Michigan computer scientists say they have found a way to exploit a weakness in RSA security technology used to protect everything from media players to smartphones and e-commerce servers. RSA authentication is susceptible, they say, to changes in the voltage supply to a private key holder.While guessing the 1,000-plus digits of binary code in a private key would take unfathomable hours, the researchers say that by varying electric current to a secured computer using an inexpensive purpose-built device they were able to stress out the computer and figure out the 1,024-bit private key in about 100 hours – all without leaving a trace.

The researchers in their paper [spam URL stripped] outline how they made the attack on a SPARC system running Linux."

  • If you're running a network server. It might be a novel way to break RSA based hardware encryption on a device you have physical access to. And that you want to spend this amount of time messing with. It is a value proposition for breaking into stolen devices. But if you have a cage and conditioned power supply, this is non-news. The PDF does state that devices like blueray are susceptible because of easy physical access. But it talks about SSL servers being susceptible. If you have physical access t
  • Considering how much trouble you'd have to go through to bypass voltage regulation, which is designed to remove this kind of noise, I think you would leave traces. Most of the article is pure crap. But it is still interesting.
