DATA PROCESSING DEVICE FOR RAILED VEHICLE CONTROL

There is provided a data processing device disposed in a carriage of a railed vehicle. The data processing device includes an operation processor. The operation processor (a) generates an initial authentication value for carriage by computing unique identification information of electronic devices disposed in the carriage by using a hash algorithm, (b) transmits an encryption key and a hash key to the electronic devices; (c) receive, from an i-th electronic device, i-th state data including i-th state information and an i-th device authentication value, and authenticate the i-th state data where "i" is an integer from 1 to n; (d) generates carriage data using state data authenticated in (c); and (e) generates a carriage authentication value based on device identification information obtained from the state data, and authenticates the carriage data by comparing the carriage authentication value with the initial authentication value for carriage.
