A flow control apparatus for controlling fluid flow in a petroleum reservoir. The flow control apparatus has a flow control mechanism, a controller operable to control the flow control mechanism to adjust fluid flow through the flow control mechanism, the controller comprising a processor operable to execute according to a control algorithm, and a non-volatile memory connected to the controller. The non-volatile memory includes instructions to cause the controller to execute an authentication mechanism operable to authenticate a control computer and to prevent operation of the controller until the authentication mechanism authenticates the control computer.
