Researchers have developed an algorithm that safeguards hardware from attacks to steal data. In the attacks, hackers detect variations of power and electromagnetic radiation in electronic devices' hardware and use that variation to steal encrypted information.

"Regardless of how secure you can make your software, if your hardware leaks information, you can basically bypass all those security mechanisms," Borowczak said.

Borowczak and Vemuri aim to restructure the design and code devices in a way that doesn't leak any information. To do this, they developed an algorithm that provides more secure hardware.
"We've basically equalized the amount of power consumed across all the cycles, whereby even if attackers have power measurements, they can't do anything with that information."
