摘要

PROBLEM TO BE SOLVED: To prevent writing as against ROM of illegal application data with falsification, etc.,. by constituting a system so as to permit the writing of application data in a storage device when a reference authenticating code coincides with an inputted authenticating code based on a discrimination result. ;SOLUTION: CPU 17 discriminates whether inputted authenticating code data DID is equal to generated reference authenticating code data or not. At the time of coincidence, that is, when the applying application data DAP is the normal one, CPU 17 writes application data DAP in the application area 14A of OTPROH 14, writes read-out system managing data DSY in the system management area 14S of OTPROM 14 and writes inputted authenticating code data D ID (or generated reference authenticating code data) in the authenticating code area 14I of OTPROH 14. Then a processing is ended.;COPYRIGHT: (C)1999,JPO
