Tony,
If you use the Java-Powered iButton as your JavaCard 2.0 device, you do not need to
license the algorithm because Dallas Semiconductor has already paid the licensing fees
for use of the algorithm inside the iButton, provided that all your RSA encryption and
decryption operations are performed inside the iButton.
If you use a card, you will have to inquire from the manufacturer of the card as to
whether they have prepaid the licensing fees for use of the algorithm inside their
cards.
