Abstract

The invention relates to a vehicle-ground wireless communication encryption method and device applied to a train monitoring system. The method comprises the following steps: establishing a communication association relationship and communication authentication by using a SM2 algorithm, and implementing management by adopting a dynamic key; encrypting and decrypting vehicle-ground wireless communication data by using a SM1 algorithm; and implementing integrity verification on the vehicle-ground wireless communication data by using a SM3 algorithm in order that the vehicle-ground wireless communication data are under identifiability protection, non-repudiation protection, confidentiality protection and integrity protection. Compared with the prior art, the vehicle-ground wireless communication encryption method has the advantages that a data encryption technology is applied to application layer equipment of the train monitoring system, so that the information safety protection performance of the vehicle-ground wireless communication is improved greatly.

Description

technical field [0001] The invention relates to a vehicle-ground wireless communication encryption method and device, in particular to a vehicle-ground wireless communication encryption method and device applied to a train monitoring system. Background technique [0002] The signal system is generally composed of train automatic control system, computer interlock control system, train automatic monitoring system, communication transmission system and peripheral general signal equipment. advanced control equipment. Among them, the train monitoring system and the train control system communicate through the train-ground wireless system based on FREE-WIFI or LTE, and exchange train status requests and report information. , ultra vires and denial of information security threats. Although the network layer of vehicle-to-ground wireless communication currently uses some general encryption technologies, there is no cryptographic technology used at the application level. Therefore...
