Abstract

The invention discloses an access method and device of a railway vehicle monitoring and maintenance system. The access method of the railway vehicle monitoring and maintenance system comprises the steps of determining a group type which a target object belongs to based on identification information of the target object; verifying the target object through the identification information of the target object and a command corresponding to the identification information; and when the target object belongs to a second group, verifying the target object through a digital certificate of the target object, wherein the authority of a first group is greater than that of the second group. The access method and device of the railway vehicle monitoring and maintenance system solve the technical problem of low safety performances of the railway vehicle monitoring and maintenance system in the prior art.

Description

technical field [0001] The invention relates to the field of rail vehicle control, in particular to an access method and device for a rail vehicle monitoring and maintenance system. Background technique [0002] The information security of the train monitoring and maintenance system is extremely important. If the information security of the train is attacked, the consequences are often very serious. Cyber ​​attacks related to railway transportation will not only seriously affect the personal safety of passengers and train staff, but also cause harm to train operating income and the overall reliability of railway transportation. As far as train operators are concerned, they not only need to bear the compensation costs caused by the attack, but also face the impact on their operating reputation. This reputational damage is more severe and lasts longer. [0003] However, the vehicle monitoring and maintenance system in the prior art still uses a single user name and password ...
