Application and Implementation of The Grounding Wire Information Management System Based on SM2

Abstract

The intelligence and automation of grounding wire information management are improved by the grounding wire management system based on network communication in maintenance of catenary, but the security problem of information transmission existed in this system. For this reason, the SM2 algorithm is used to digitally sign the grounding wire information, and ensure it can not be tampered and non-repudiation. Under the C/S architecture, the grounding wire information management system with digital signature technology is established. The server realizes the information interaction between the grounding wire monitoring unit and the client. The client visually displays the status, location, and picture information of the grounding wire through the visual interface. The results show that the application of the SM2 digital signature technology for the grounding wire information management system insure the security of the grounding wire information.
