Researchers Find Way to Recover Cryptographic Keys by Analyzing LED Flickers
2023-06-26 16:46

In what's an ingenious side-channel attack, a group of academics has found that it's possible to recover secret keys from a device by analyzing video footage of its power LED. "Cryptographic computations performed by the CPU change the power consumption of the device which affects the brightness of the device's power LED," researchers from the Ben-Gurion University of the Negev and Cornell University said in a study. "This is caused by the fact that the power LED is connected directly to the power line of the electrical circuit which lacks effective means of decoupling the correlation with the power consumption," the researchers said.
