support system server through the communicator; the controller is configured to respond to a
firmware upgrading instruction of the intelligent household electrical appliance, send a first
firmware upgrading request to the firmware upgrading
server, and receive a first
certificate chain returned by the firmware upgrading server in response to the first firmware upgrading request; sending a target fault instruction to an operation
support system server under the condition that the
verification of the first
certificate chain by adopting the pre-installed
root certificate is not passed; receiving a target
root certificate returned by the operation
support system server in response to the target fault instruction, and updating the pre-installed
root certificate into the target root
certificate; the target root certificate is used for firmware upgrading of the intelligent household electrical appliance, so that the controller can update the root certificate in time, and the reliability of firmware updating of the intelligent household electrical appliance is improved.
