1. A method for partitioning of cryptographic functionality so as to permit delegation of at least one of a plurality of distinct portions of the cryptographic functionality from a delegating device to at least one recipient device, the cryptographic functionality being characterizable as a graph comprising a plurality of nodes, the method comprising the steps of: associating a given set of the nodes with a corresponding one of the plurality of distinct portions of the cryptographic functionality; and transmitting from the delegating device to the recipient device information representative of one or more of the nodes, such that the recipient device is thereby configurable for authorized execution of a corresponding one of the plurality of distinct portions of the cryptographic functionality.
