Abstract
A cryptographic engine for modulo N multiplication, which is structured as a plurality of almost identical, serially connected Processing Elements, is controlled so as to accept input in blocks that are smaller than the maximum capability of the engine in terms of bits multiplied at one time. The serially connected hardware is thus partitioned on the fly to process a variety of cryptographic key sizes while still maintaining all of the hardware in an active processing state.
