摘要:
A modular multiplication apparatus comprises a calculation unit which comprises processing units including a multiplier-adder unit and performs a modular multiplication by carrying out pipeline processes by the processing units; and a calculator configured to, before a first pipeline process, carry out a predetermined calculation for a processing result of one of the processing units in a pipeline process immediately before the first pipeline process, and when the first pipeline processes supply a calculation result of the predetermined calculation to a processing unit at an initial stage of the first pipeline process.
