Abstract

A server issues challenge data and transmits the challenge data to a client. The client stores pre-calculated data that is a result obtained by executing at least a part of calculation for setting a response key on the server side, sets a response key on the client side without using the pre-calculated data, generates response data from the challenge data received from the server, based on the response key, and transmits the generated response data and the stored pre-calculated data to the server. The server receives the response data and the pre-calculated data, sets the response key on the server side, based on the pre-calculated data, verifies the response received from the client, based on the issued challenge data and the set response key, and notifies the client of a result based on the verification.
