Operation and restoration method of rail transit signal system based on domestic encryption technology

Abstract

The invention relates to an operation and restoration method of a rail transit signal system based on domestic encryption technology. According to the method, it is judged that a domestic encryption security chip possibly fails through the signal system itself, if a fault occurs, the domestic encryption security chip is isolated, the signal system is enabled to restore to a state where the encryption technology is not adopted, and meanwhile, warning information is given to a maintenance terminal in the shortest time; and compared with the prior art, the method has the advantages that the normal operation of the signal system is still not affected even under the condition that the domestic encryption security chip fails, and the like.

Description

technical field [0001] The invention relates, in particular, to an operation and recovery method of a rail transit signal system based on domestic encryption technology. Background technique [0002] The "Network Security Law", which was implemented on June 1, 2017, has listed the transportation field as a key information infrastructure, and implemented key protection on the basis of the network security level protection system. Rail transit is a key area related to the national economy, the people's livelihood, and public interests. For the train control system, domestic encryption technology can be used to improve the information security level of train-to-ground wireless communication and prevent various high-tech crimes. [0003] The domestic encryption technology is applied to the rail transit signal system, which is realized by adding the national security chip hardware or software algorithm on the basis of the existing signal system, and encrypts the data of the vehic...

Problems solved by technology

Since the signaling system has very strict requirements on reliability, the reliability of the national secret security chip itself still needs a process of improvement. If the chip fails, it will cause a certain train or even a certain area in the signaling system to fail to perform normal operations Encryption and decryption, which in turn affect the corresponding operating status and control commands cannot be interacted. According to the fail-safe principle of the signal system, it will cause delays or even interruptions of train operation. This is unacceptable for public transportation, so it is necessary to comprehensively compare information security levels for the time being Reduce the risk of public transport delays and interruptions, and manage the application of national secret protection technology in signaling systems in a safe and reliable manner
