"Experts Recover AES256 Encryption Key From a PC's Electromagnetic Emissions"
With the use of an inexpensively self-built device, researchers from Fox-T and Riscure were able to recover encryption keys from the electromagnetic waves emitted by a computer in close distance. The device built by researchers performs a notable side-channel attack by the name of “Van Eck phreaking” to specifically capture AES256 encryption keys. This article further discusses what parts were used to build this device, associated costs, how it performs to capture encryption keys, where this attack was tested by researchers, and other research conducted on Van Eck phreaking attacks.
