A data structure of data to be authenticated has a header authentication data area (D), and an authentication data area (D) in addition to a header area (D) and a data area (D). The header authentication data area (D) authenticates validity of the header area (D), and the authentication data area (D) authenticates the validity of the header authentication header area (D) and the data area (D). Since two kinds of authentication are carried out, the cause of the failure in authentication can be identified easily when authentication is failed.
