Summary:A plurality of group signature processes is executed in parallel with a small number of processing devices and small power consumption, without lowering an average response speed. A signature processing device includes subsystems for each type of basic operations included in a signature processing procedure. Each subsystem has a configuration in which one or more basic operation execution units and a dispatcher that monitors operation states thereof and instructs to execute an operation are interconnected. A plurality of signature generation requests or signature verification requests is accepted as a single input, and a plurality of requests is simultaneously processed in parallel. At this time, each subsystem assigns operations in different requests to unoccupied basic operation units and causes the basic operation units to simultaneously execute the operations, without being occupied with a single request.
