Abstract

The present application provides a data recovery method, device, system, equipment, and storage medium based on a security-critical system, and relates to the technical field of data security. Wherein, the data recovery method based on the safety-critical system includes: after initialization or restart, sending a data request message to other devices in the safety-critical system, and preloading the locally stored target safety data into the memory; wherein, the The data request message is used to request the other device to send the stored target security data to the first device; receive the target security data returned by at least one of the other devices; according to the target security data returned by the other device and The locally stored target security data is confidently compared, and if the comparison is consistent, triggering the use of the target security data that has been loaded into the memory to complete data recovery. The solution of this application can effectively improve the data recovery efficiency of a security-critical system, and avoid potential safety hazards caused by manual intervention.

Description

technical field [0001] The present application relates to the technical field of data security, in particular to a data recovery method, device, system, equipment and storage medium based on a security-critical system. Background technique [0002] The safety-critical system represented by the railway signal system is moving towards the trend of reducing the arrangement of equipment along the line in the direction of system evolution. The representative is the introduction of positioning technology including Beidou or GPS to realize the position positioning of the train. Correspondingly, secondary detection equipment is no longer or reduced, including track circuits or axle counting, so as to reduce equipment investment and later maintenance costs, so as to adapt to the application in a wide area. [0003] Taking the Incremental Train Control System (ITCS) as an example, after the system is initialized or the equipment is restarted, the whole line or the corresponding line a...
