Locomotive wireless multiple-unit system

Abstract

This invention provides a locomotive wireless multiple-connection system, including a locomotive, a wireless control unit, a wireless communication unit, a ground communication unit, a certificate registration authority, and a certificate authority. The wireless control unit connects to the ground communication unit via the wireless communication unit. The wireless control unit sends a registration request to the certificate registration authority via the ground communication unit. The certificate registration authority responds to the registration request, verifies the user information, and generates verification information upon successful verification. Upon receiving the verification information, the certificate authority generates a digital certificate based on the user information and sends the digital certificate to the wireless control unit. The wireless control unit on the locomotive connects and communicates with the certificate registration authority and the certificate authority to complete the issuance of digital certificates. This ensures that when the wireless control units on both locomotive and locomotive communicate, they must encrypt and decrypt information using the issued digital certificate, guaranteeing the confidentiality and integrity of information transmitted between the locomotive and locomotive.
