Abstract

A server generates challenge data by generating falsification verification data of first data, using a server key, based on a predetermined algorithm, and transmits the first data and the challenge data to a client. The client receives the first data and the challenge data, generates response data from the received challenge data using a response key in the client, and transmits the received first data and the response data to the server. The server receives the transmitted first data and response data and reproduces challenge data by generating the falsification verification data using the server key, based on the predetermined algorithm. Then, the server verifies the received response data using the reproduced challenge data and a response key set in the server, and if a verification result is positive, the server notifies a positive authentication result.
