To achieve secure, trustworthy, convenient, and flexible network security configuration for switches in nuclear power instrumentation and control (I&C) systems, a rapid configuration software based on LabVIEW was designed. This software enables the creation of new configuration schemes for different requirements and allows quick selection of suitable configuration combinations from existing strategies to implement switch network security configurations. Additionally, it provides functions such as viewing detailed switch network security configuration statuses and deleting configurations. This approach offers a reliable, convenient, and efficient configuration method for network security settings of switches in nuclear power plant I&C systems.
