Train-mounted encryption device and train-mounted encryption machine

Abstract

The invention discloses a train-mounted encryption device and a train-mounted encryption machine. The train-mounted encryption device comprises a first control module, a second control module, an encryption module, a communication interface module and a wireless communication module, the first control module generates an encryption request signal and a sending data signal according to an application demand, and generates a first communication signal according to the first encryption data signal; the second control module forwards the encryption request signal, the sending data signal and the first encryption data signal; the encryption module encrypts the sent data signal according to the encryption request signal to generate a first encrypted data signal; the communication interface module forwards the first communication signal; the wireless communication module generates a first wireless signal according to the first communication signal so as to communicate with a ground server; the encryption equipment is inserted into the train-mounted case to perform remote wireless sending and remote wireless receiving of encrypted data, so that the safety, stability and reliability of train network data transmission are improved.

Description

technical field [0001] The invention belongs to the technical field of train information security, and in particular relates to a train-mounted encryption device and a train-mounted encryption machine. Background technique [0002] At present, with the rapid development and popularization of train informatization network technology, the degree of train informatization is getting higher and higher. Passenger Internet access system, locomotive operation monitoring system, some equipment In the development of the country, civilian 4G and 5G networks and ground systems have been used for data communication. Due to the security of the train network, it is required that the train network data cannot be stolen and modified by attackers, and it is necessary to use an encryption machine to encrypt the content transmitted on the public network. And due to the variability of the train operating environment, it is required that the encryption machine equipment must be suitable for very...
