REMOTE AUTHENTICATION MODE NEGOTIATION METHOD FOR COMBINED DEVICE, AND RELATED DEVICE

Disclosed in the embodiments of the present application are a remote authentication mode negotiation method for a combined device, and a related device; the combined device may at least comprise a first unit, and the negotiation process between the combined device and a remote authentication device to determine a target remote authentication mode for remote authentication comprises: the first unit issues a mode negotiation request message to the remote authentication device; the remote authentication device refers to the mode negotiation request to determine a target remote authentication mode, and generates a mode negotiation response message and sends same to the first unit; and, on the basis of the mode negotiation response message, the first unit determines the remote authentication mode. Thus, the target remote authentication mode to be employed can be determined by means of the negotiation between the combined device and the remote authentication device, providing a foundation of data for subsequent ord
