1. A method for guaranteeing a reliability of real-time scrambling and message transmission by a train control center system, comprising the following steps:
step S1, starting a system for offline message loading and reading;
step S2, obtaining messages to be scrambled;
step S3, sending the messages to be scrambled to a scrambling operation board for scrambling;
step S4, performing an inverse decoding on an operation board;
step S5, performing a comparison after the inverse decoding, further comprising:
message data subjected to the inverse decoding are compared with originally selected message data, if the message data and the originally selected message data are consistent, it means that the scrambling is correct and scrambled messages are valid, and otherwise, the scrambled messages are invalid; and
step S6, outputting effective message data.
