Keys leaking through the air at RSA

NumberField writes: The RSA Conference is underway in San Francisco. A theme among the opening speakers is that the attackers are winning, and even well-funded organizations like NASDAQ can't secure their networks reliably. The show floor is lively, but dominated by the typical firewalls and "compliance solutions". One interesting exception is a scary side channel analysis demo in the Cryptography Research booth using GNU Radio to capture secret keys from various smartphones from about 10 feet away. (The method is related to early computer music using AM radio interference.)

Faraday cage?

Does this mean we should carry our phones around in Faraday cages to keep our secret keys from leaking out? (As an AT&T iPhone customer, I'm not sure I'd even notice the reduction in coverage...)
