A Very Noisy Signal: Intel Circuit Squashes Side-Channel Sniffing
IEEE Spectrum: Encryption sounds beautifully simple at its core: Encoded messages can’t be read unless you’re authorized with a key to decode them. But through a sneaky attack called side-channel sniffing, unauthorized bad actors can figure out the key by measuring the encryption engine’s power consumption or electromagnetic outputs and having a computer do a bit of math.
Now, an Intel-funded team at the Georgia Institute of Technology has created a circuit with significantly increased resistance to those side-sniffing attacks.
