Would you happen to know what kind of signature scheme they use?
- mschuster91 7y agoIIRC the German system is proprietary, the specs are available only after payment of a couple hundred euros.
- dependenttypes 7y agoI am grossed out by proprietary protocols but proprietary encryption algorithms just make me laugh. Who even though that this would be a good idea? Are they seriously trusting their money with this?
- Fnoord 7y agoMy bank seems to use a similar scheme. It appears akin to TOTP with 8 numbers. But the secret is inside the black box. They also have something like a QR code but with RGB colors (does not work with blue light reducing features).
- icebraining 7y agoI don't know about the German system, but here they use EMV-CAP: https://en.wikipedia.org/wiki/Chip_Authentication_Program https://en.wikipedia.org/wiki/Chip_Authentication_Program
