摘要
讨论了基于 Internet 的远程监控系统的安全需求。在分析基于 IPSec 的虚拟专用网(VPN)技术的基础上,给出了基于 VPN 技术的远程监控系统安全模型,可以实现经 Internet 对现场工业过程及设备进行远程操作的安全性,方便了使用具有 USB 接口的电子安全匙的用户漫游。分析表明,该方案既可保证远程操作安全,又可节省网络和通信费用,适用于一般的远程操作监控系统。
Security requirements of the remote monitor system based on Internet are discussed. With analyzing the key issues of VPN, the security model of remote monitor system based on IPSec VPN is presented. This security model would provide security guarantee for the teleoperation to the industry process and plant-floor devices, and facilitate the mobile user by using an electronic security key with USB interface. The analysis indicates that this security model can not only ensure teleoperation security but also reduce the cost of network and communication, so it would be widely used in remote monitor system.
