摘　　要：针对工业控制中EPA网络的网关安全问题,基于EPA组态软件,提出EPA网络安全组态技术。设计EPA网络安全组态模块,通过组态功能块定义访问控制对象,设置加密密钥、校验密钥、校验算法。访问控制对象经编译后下载到安全设备中,决定安全设备的运行状态。测试结果表明,该技术可提升工业控制领域EPA网络控制的安全性和可靠性。Aiming at Ethernet for Plant Automation（EPA） network gateway security control problem of industrial control, this paper proposes EPA network security configuration technology based on EPA configuration software. It designs EPA network security configuration module, realizes access control object through configuration of function block, set encrypt key, checkout key and checkout arithmetic. Access control object is download to safe device after translation and edition to decide the run state of safe device. Test result shows that this technology can effectively satisfy the design of EPA control system and the needs of security, and enhance the safety and reliability for EPA network control in the field of industrial control network.
