摘要：This paper puts forward a solution for ensuring data security of the internal network of railway while the earthquake early-warning and monitoring system for high-speed railway (EEMS) exchanges data with national or provincial earthquake networks. The solution is based on the principle of Net Gap, and fulfils the security needs of data exchange between the internal and external network of railway when the EEMS and national or provincial earthquake networks are interconnected. It guards the data exchange between the two and fulfils security needs during the exchange while ensuring security isolation, thus is more secure than conventional security methods.
