PROBLEM TO BE SOLVED: To prevent an unauthorized action such as spoofing by safely and surely processing data by providing a ternary authentication method uniquely determining three authenticators. SOLUTION: By using at least two authenticators registered at an authenticating side and an authenticated side before authentication and a newly generated authenticator, codes are encrypted, exchanged (transmitted/received) and decrypted between the authenticating side and the authenticated side, thereby authenticating that the authenticators are identical to each other.
