Researchers Find Way to Extract 4096-Bit RSA Key via Sound

Scientists have proved that they can extract a 4096-bit RSA key from a laptop using an acoustic side-channel attack that enables them to record the noise coming from the laptop during decryption, using a smartphone placed nearby. The attack can be used to reveal a large RSA key in less than an hour.
