ABSTRACT:
The Smart Card URL Programming interface (UPI) builds a local web or card server around a card terminal and the inserted smart card. This server can also support secure object storage, which stores serialized, secure signed, compressed objects (or applications or data) for delivery to the card or for off-loading from the card. The secure object storage is also web addressable. The object storage program stores objects with the option of signing and/or encrypting and retrieves objects which may require cryptographic credentials. If a user desires to run applications on a card that exceeds the memory capacity of the card, information about the applications, including pointers and their digital signatures, is acquired and stored on the card by the card server. The card server manages the applications on a card and their movement on and off the card.
