Authentication method and authentication system based on forking, and forking authentication device

An authentication system based on forking, comprising at least two receiving devices for authenticating an original device, comprising:

• a setting module, configured to set authentication credentials on the receiving devices and the original device respectively;
• a forking network element, connected to the original device and the receiving devices, and configured to fork a calling request after receiving the calling request from the original device, to transmit the forked calling request to the corresponding receiving devices, and to forward to the original device a plurality of challenging values transmitted by a plurality of the receiving devices;
• the original device, connected to the setting module, and configured to transmit a calling request, to retransmit the calling request after receiving the plurality of challenging values, and to carry relevant authentication credentials in the retransmitted calling request;
• and
• the receiving devices, connected to the setting module, and configured to perform authentication on the original device according to the authentication credentials, after receiving the retransmitted calling request.

A forking authentication device located in an original device, comprising:

• a setting module, connected to a transmission module, and configured to set authentication credentials;
• the transmission module, connected to the setting module, and configured to transmit a calling request;
• a receiving module, connected to the transmission module, and configured to receive challenging values from a forking network element;
• and
• a retransmission module, connected to the receiving module, and configured to retransmit the calling request, and to carry in the calling request the authentication credentials corresponding to the challenging values.
