Low Voltage Is Key To Energy-Efficient Chip 127

Posted by kdawson on Tuesday February 05, 2008 @07:15PM from the breaking-the-barrier dept.

An anonymous reader writes in with news from the International Solid State Circuits Conference in San Francisco of a new energy-efficient chip designed by researchers at MIT. It's said to be able to run on 1/10 the power of current chips. Texas Instruments worked with MIT on the design, which is maybe five years from production. "The key to the chip's improved energy efficiency lies in making it work at a reduced voltage level, according to... a member of the chip design project team. Most of the mobile processors today operate at about 1 volt. The requirement for MIT's new design, however, drops to 0.3 volts."

While the dangers of unencrypted data transfer on a public wireless network have been around for some time, this tool presents the first example of an automated webmail hijack. Since the tool uses a cookie based attack, it works whether or not the user changes his or her password. This tool could potentially automate the attack of any user on a wireless network, so long as the website the user logs into does not encrypt its login information."
