Java Card and Elliptic Curves
Hi all,
has anyone ever used Elliptic Curve cryptography on a Java Card? I can't find any documentation and sample code about this topic, although it should be implemented in the new java card specifications.
I would like to use ECC instead of RSA for encrypting a message and verifying a signature on a java card with a EC pubkey.
If anyone could provide me with sample code or hints, that would be very helpful!
Thanks in advance,
Matthias

No, it can (not should) be implemented. The implementation of all cryptographic algorithms is optional.

The sample code wouldn't be too complicated to create (should be very similar to using RSA) but where do you execute this code? All emulators/simulators and the real Java Cards I know do not support ECC.
I only heard rumours that "Trusted Logic" has Java Cards which support ECC, but I haven't checked that.
