SECURE OFF-PREMISES ACCESS OF PROCESS CONTROL DATA BY A MOBILE DEVICE

A system and method for facilitating secure communication between a process control application executing on a mobile device and a mobile server communicatively coupled to a process control environment includes the instantiation, in a cloud-based environment, of a relay connection element. Each of the mobile server and any mobile applications executing on mobile devices authenticates itself to therelay connection element. The relay connection element, the process control applications executing on the mobile devices, and the mobile server, each receive the necessary credentials through a series of authenticated requests between a variety of elements in the cloud-based environment, such that elements in the system necessarily authenticate one another before any information is provided to another element. 一种用于促进在移动设备上执行的过程控制应用与通信地耦合到过程控制环境的移动服务器之间的安全通信的系统和方法，包括在基于云的环境中实例化中继连接元件。移动服务器和在移动设备上执行的任何移动应用中的每一个向中继连接元件认证其自身。中继连接元件、在移动设备上执行的过程控制应用以及移动服务器中的每一个通过基于云的环境中的各种元件之间的一系列经认证的请求来接收必要的凭证，使得系统中的元件在任何信息被提供给另一元件之前必须彼此认
