摘　　要：过程控制中数据安全问题日益凸显,将加密技术应用到该领域尤为必要。考虑过程控制实时性要求,利用高级加密算法对数据加密。采用中控CS4000过程控制装置为现场设备,西门子S7-300PLC为过程控制设备,配置组态软件的PC若干作为上位机和管理机,对上位机获取数据加密处理确保数据安全。Data security in process control grows rapidly, encryption technology is applied to the field is necessary. Considering real-time process control requirements, using advanced encryption algorithm data. Using SUPCON CS4000 process control device as on site device, Siemens S7-300 PLC as device in the process control, some computers with configuration software are as host machines and the management machines respectively. Process data of the Upper computer is encrypted to ensure data security.
