DEVICE AND METHOD FOR DISTRIBUTED AUTHENTICATION, DISTRIBUTED AUTHENTICATION SYSTEM AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To fast perform authentication processing without using a dedicated hardware. SOLUTION: A parallel processing processor 11 executing parallelly operation processing for secretly distributed processing and secret restoration processing and communication protocol processing configures a device for distributed authentication and this small-sized and convenient device can carry out fast distributed authentication processing by executing parallelly a matrix (simultaneous polynomial) operation in the secretly distributed processing and the secret restoration processing and communication protocol processing with each member without using a dedicated hardware.
