    摘要: A method for enhancing reliability of data is provided. A computer configured to provide output datum (Ds) from input datum (De), includes at least two data processing modules, and a computing member connected to each module. The method includes computing, with each module, intermediate datum (DIA, DIB) from the input datum (De) calculating, with each module, an intermediate security code (CSIA, CSIB) from the corresponding intermediate datum (DIA, DIB), transmitting to the computing member with each module, the intermediate security code (CSIA, CSIB) and the intermediate datum (DIA, DIB), computing, a security code (CS) from the intermediate security codes (CSIA, CSIB), selecting, an intermediate datum from among the received intermediate data (DIA, DIB) the output datum, (Ds) of the computer including the selected intermediate datum, and transmitting to a receiving device, the security code (CS) and output datum (Ds). A computer, communication unit, a railway management system and computer readable media are also provided.
