How Scientists Plan to Stop Nasty Side-Channel Attacks

Shafi Goldwasser at MIT and Guy Rothblum at Microsoft Research are proposing a technique that could alleviate the threat of such attacks, which often rely on an attacker being able to listen to the "noise" of computer processes. Side-channel attacks are frequently timing storage transactions and are measuring the power use of a systems to make conclusions of a system's activity and ultimately open a door to critical data.
According to Goldwasser and Rothblum, such an attack would only require a piece of code loaded on a cloud server, which could eavesdrop on the activity of applications. A side-channel attack is still a very sophisticated attack in secure server environments, as it would req... »read more
