a credential controller offboard the vehicle configured to provide a security message to a requesting device in response to receiving a security request therefrom, the security message including a security credential generated by the credential controller for the requesting device; and
a security controller onboard the vehicle configured to:
receive a command request from the requesting device, the command request including the security credential;
relay the command request to the credential controller for processing of the security credential;
receive a command message from the credential controller in response to the command request;
control the charging security system to remain in a first state in response to the command message indicating the command request as unapproved; and
control the charging security system from the first state to a second state in response to the command message indicating the command request as approved;
wherein the charging security system includes an alarm, the first state arming the alarm to generate an alert in response to the charging station being electrically disconnected from the vehicle, the second state disarming the alarm to prevent the alert from being generated in response to the charging station being electrically disconnected from the vehicle.
