ABSTRACT:
A method and apparatus for implementing portions of a provisional signature scheme are disclosed. In one embodiment, the method comprises creating a provisional signature by performing an operation on a message and completing the provisional signature to create a final signature on the message. Such a scheme may be used for server assisted signature schemes, designated confirmer signature schemes and blind signature schemes.
