SECURITY SYSTEM FOR A MOVEABLE BARRIER OPERATOR
In one aspect, a movable barrier operator is provided having a motor, a transmitter, a receiver, and a controller. The controller is configured to receive through the receiver a first public key from a remote control; determine a second public key and a second private key; and determine a shared secret session key using the second private key and the first public key. The controller is configured to operate the transmitter and receiver to bidirectionally communicate with the remote control so that the movable barrier operator can learn a fixed code and a changing code of the remote control. The bidirectional communications are encrypted using the shared secret session key. Upon the movable barrier operator successfully learning the remote control, the movable barrier operator transmits a long-term key to the remote control that is used to encrypt subsequent communications between the movable barrier operator and the remote control.
