Chip bugs can lead to major security disasters

Chip bugs can lead to major security disastersChip bugsShamir suggests that it's impractical to test all cases of 64*64-bit multiplication. But given the lifespan of a chip design, and given that the test only needs to be run once, wouldn't it be practical to design a "grid" or "distributed" test,...

Photoshop plug-in developer onOne acquires Liquid Resize technology.

Calling all digital photographers: If you haven't seen this video from Siggraph 2007, you must check it out. Ignore the monotonous voice of the narrator--he doesn't sound nearly as excited as he should be--and watch his demo of "Seam Carving for Content-Aware Image Resizing" presented by Shai Avidan and Ariel...

Chip bugs can lead to major security disasters

Adi Shamir, professor at the Weizmann Institute of Science in Israel and "S" in RSA, sent out a warning about a hypothetical scenario in which bugs in widely used processors could be exploited undetected by "sophisticated" intelligence agencies and lead to major security disasters. These bugs chips,...

Spotlight on 'seam carving'

At the 6sight conference in Monterey Calif., Ariel Shamir, a visiting scientist with Mitsubishi Electric Research Laboratories, discusses "seam carving" technology, which lets an image be expanded or shrunk without distorting the important parts.

GPS accuracy for a robotic neurosurgeon

The MiniAture Robot for Surgical Applications MARS is already FDA-approved for orthopedic and spinal surgery. Now, Israeli scientists have given it GPS accuracy for keyhole neurosurgery. This is a minimally invasive procedure used for tumor biopsies or deep brain stimulation, but you need to know exactly where you operate. So...

RSA 2007 keynotes: Notable quotes

The morning RSA keynotes were mostly warmed over common wisdom--layer approachs, risk management, intelligence sharing, managing user identities, governance, focusing on users, etc.--about information security, with the exception of the cryptographer panel, which had some good moments. I pulled out some quotes from the presentations to give a flavor of...

A Key Recovery Attack on the 802.11b Wired Equivalent Privacy Protocol (WEP)

This paper presents a practical key recovery attack on WEP, the link-layer security protocol for 802.11b wireless networks. The attack is based on a partial key exposure vulnerability in the RC4 stream cipher discovered by Fluhrer, Mantin, and Shamir. This paper describes how to apply this aw to breaking WEP,...
