1. A wireless power transmitter comprising:
a power converter configured to transfer wireless power to a wireless power receiver; and
a controller configured to communicate with the wireless power receiver to control transmission of the wireless power,
wherein the controller is configured to:
receive, from the wireless power receiver, an authentication request message for authentication of the wireless power transmitter, and
transmit, to the wireless power receiver, a data stream including a plurality of auxiliary data transport (ADT) data packets in which at least a part of an authentication response message is divided,
wherein the data stream includes at a beginning an auxiliary data control packet informing a start of the data stream, and
wherein the controller is further configured to:
transmit, to the wireless power receiver, an auxiliary data control packet,
receive, from the wireless power receiver, a first response for the auxiliary data control packet,
transmit, to the wireless power receiver, a first ADT data packet among the plurality of ADT packets based on the first response,
receive, from the wireless power receiver, a second response for the first ADT data packet, and
transmit, to the wireless power receiver, the first ADT data packet again, based on a value included in the second response.
