Zusammenfassung:A device authentication method, apparatus (900, 1000), electronic device and slave device (200). The method comprises: sending an authentication enable signal to a first target slave (200), to enable the first target slave device (200) to change identification information thereof from first identification information to second identification information (201); and sending, on the basis of the second identification information, first specific identification information to the first target slave device (200), to enable the first target slave device (200) to change the identification information thereof from the second identification information to the first specific identification information (202). The device authentication method, apparatus (900, 1000), electronic device and slave device (200) achieve highly efficient authentication of a slave device connected to a master device. The master device (100) can authorize the cascaded slave device (200) via a connection interface, uses a small number of pins, and
