New Dongle technology, using Smart Cards

Hey that chinese smart card dognel just arrived to the europian market. So its new here Actually, I was comparing the new technology with the old dongle technologies. Im not telling that its the best protection. But its something requires more than medium skills. I dont believe that generic emulators will be out (as crackers did for HASP4 for example). That RSA public/private (private stored inside the smart card) will bring lot of troubles to developers and will take long time to study and analyze that thing. Im almost sure that the cracker must have at least good skills on cryptography to prevent (or remove) this protection.

It is not about cryptography. It is about the way of code encryption/decryption (or translation in case of virtual machines, own environments, virtual CPUs, etc.). You can use any algorithm, even hybrid, and you will lose becuase in some moment your code has to be detranslated/decrypted. Till the day someone will propose a new way of abstraction, everything will be crackable in a short time. The hardest software protections take now ~10 days for the deprotection on the first approach and then ~10 hours for the deprotection after getting acquainted with it. That is too short.
