1. A system for protecting recorded train event data, comprising:
- at least one external memory device comprising encrypted authentication data, the encrypted authentication data comprising authentication data encrypted with at least one first key; and
a train event recording system on a train and in communication with a train management computer, the train event recording system configured to;
record train event data for the train from the train management computer;
determine if the at least one external memory device comprises the encrypted authentication data when the at least one external memory device is in communication with the train event recording system;
decrypt the encrypted authentication data based at least partially on at least one second key;
determine if the authentication data is valid; and
facilitate a transfer or cause the transfer of at least a portion of the event data to the at least one external memory device if the authentication data is determined to be valid.

9. A method of preventing unauthorized transfer of train event data from a train event recording system, comprising:
-
providing a plurality of memory devices, wherein each memory device comprises authentication data encrypted with at least one first key; storing at least one second key on a computer-readable medium in communication with the train event recording system; determining, with the train event recording system or a train management computer, if the encrypted authentication data is on at least one memory device of the plurality of memory devices; decrypting, with the train event recording system or the train management computer, the encrypted authentication data based at least partially on the at least one second key; determining if the at least one memory device is valid based at least partially on the authentication data; and preventing at least a portion of the event data from being transferred to the at least one memory device if the at least one memory device is not determined to be valid. - View Dependent Claims (10, 11, 12, 13, 14)
