PROBLEM TO BE SOLVED: To prevent erroneous data from being transmitted without being detected due to an operational failure of a replacement function when transmitting an error detection code to be attached to a data which is transmitted based on a processing result made by a first processing unit in place of an error detection code generated based on a processing result made by a second processing unit.SOLUTION: The signal security control system determines match/mismatch between a confirmation code which is added to a processing result made by a first processing unit 10A and an error detection code which is generated based on a processing result made by a second processing unit 10B. Determining as match, the confirmation code is replaced with a matched error detection code and is added to the processing result made by the first processing unit and transmitted therefrom. Determining as mismatch, the data transmission is terminated. |
