Researchers at the Georgia Institute of Technology are investigating so-called side channel signals, low-level emissions from a computer that could allow savvy cyber attackers to illegally access information. By learning more about the signals, researchers may be one day be able to help mitigate the threat.
The Georgia Tech team has developed an algorithm for measuring the strength of the leaks, which will help prioritize security efforts. They now are studying smartphone emissions, which they say may be even more vulnerable. So far, they have looked only at Android devices.
