Abstract
A method for securing communicating with a human machine interface (HMI) terminal over a mission critical wireless link (MCWL) link is provided. The method includes sending, by a MCWL node, a connection request to the HMI terminal; upon receiving an acknowledge from the HMI terminal, authenticating the HMI terminal; and upon authentication of the HMI terminal, establishing a secure connection channel is between the MCWL node and the HMI terminal, wherein commands to at least control the MCWL node are sent from the HMI terminal over the secure connection channel.
