A group of researchers has proved that it is possible to break the encryption used by many mobile payment apps by simply measuring and analysing the electromagnetic radiation emanating from smartphones. “We show that modern cryptographic software on mobile phones, implementing the ECDSA digital signature algorithm, may inadvertently expose its secret keys through physical side channels: electromagnetic radiation and power consumption which fluctuate in a way that depends on secret information during the cryptographic computation,” … More →
