I don't know the details but it doesn't sound great if you can exfiltrate secret material – the seed? – from a device.
A good smartcard should generate its own keys, on device, and only divulge them when persuaded to do so by an electron microscope.
- rendaw 5y agoYou can't exfiltrate it - you can generate a seed externally and load it in, and back it up if you choose.
- gorgoiler 5y agoYou can extract the seed, clone it into a new device, and get the exact same device with the same private key material?
- ThePowerOfFuet 5y agoYes, but you can extract it only once; the device will refuse to provide it if it's already been provided.
