1. A method in a wireless power transfer system, the method performed by a wireless power receiver and comprising:
in response to a digital ping initiated by a wireless power transmitter, transmitting, to the wireless power transmitter during a ping phase, a response signal;
transmitting, to the wireless power transmitter during a configuration phase, a configuration packet including first control information related to whether the wireless power receiver supports an authentication function to authenticate the wireless power transmitter;
receiving, from the wireless power transmitter during a negotiation phase, a capability packet including second control information and a potential power value of the wireless power transmitter, wherein the second control information is related to whether the wireless power transmitter supports the authentication function; and
receiving power from the wireless power transmitter.
