PROBLEM TO BE SOLVED: To perform mutual authentication by using NTRU public key encryption method. SOLUTION: Mutual authentication between a server and a client is performed with the protocol using an NTRU private key encryption method. By adding random numbers which are going to be seeds of a session key and their hash value to transmission data, it makes possible to check whether description failure is generated. The session key is formed on the basis of the random numbers for the session key, and data transmission and reception after authentication are performed by encryption. Process of the NTRU encryption method is light and the protocol is simple, so that mounting to an assembly type apparatus is enabled.
