DRM alert
p2pnet.net News:- "Meta moral," posts security expert Bruce Schneier on his blog. "If Alice controls the device, and Bob wants to control secrets inside the device, Bob has a very difficult security problem. These ’side-channel’ attacks - timing, power, radiation, etc - allow Alice to mount some very devastating attacks against Bob’s secrets."
A new paper, "describes a timing attack against RSA, one that bypasses existing security measures against these sorts of attacks," he says.
"The attack described is optimized for the Pentium 4, and is particularly suited for applications like DRM."
Schneier says he’ll be writing more on this for a Wired story, "but for now you can read the paper, the Slashdot thread, and the essay I wrote in 1998 about side-channel attacks (also this academic paper)."
