AUTHENTICATION ACCESS METHOD AND AUTHENTICATION ACCESS SYSTEM FOR WIRELESS MULTI-HOP NETWORK
First Claim
1. An authentication access method applicable to a wireless multi-hop network, comprising:
- defining an uncontrolled port and a controlled port of a terminal device and a coordinator, wherein the uncontrolled port pass an authentication protocol data packet and management information and the controlled port pass an application data packet,;
broadcasting, by the coordinator, a beacon frame comprising authentication and key management suites supported by the coordinator;
selecting, by the terminal device upon reception of the beacon frame of the coordinator, one of the authentication and key management suites, and then transmitting to the coordinator a connection request command comprising the authentication and key management suites selected by the terminal device;
performing, by the coordinator upon reception of the connection request command of the terminal device, an authentication process with the terminal device according to the authentication and key management suites selected by the terminal device; and
upon successful authentication, opening the controlled port to allow an access of the terminal device to the wireless multi-hop network while transmitting a connection response command to the terminal device; and
opening, by the terminal device upon reception of the connection response command of the coordinator, the controlled port to thereby access the wireless multi-hop network.

Abstract
Authentication access method and authentication access system for wireless multi-hop network. Terminal equipment and coordinator have the capability of port control, the coordinator broadcasts a beacon frame, and the terminal equipment selects an authentication and key management suite and transmits a connecting request command to the coordinator. The coordinator performs authentication with the terminal equipment according to the authentication and key management suite which is selected by the terminal equipment, after authenticated, transmits a connecting response command to the terminal equipment. The terminal equipment and the coordinator control the port according to the authentication result, therefore the authenticated access for the wireless multi-hop network is realized. The invention solves the security problem of the wireless multi-hop network authentication method.
