1. A communication method for a mesh network system, said mesh network system including a plurality of communication terminals such that an adjacent communication link is established between adjacent communication terminals among the plurality of communication terminals after authenticating a counterpart adjacent communication terminal so as to enable wireless multi-hop communication in the mesh network system,the communication method comprising:

  • an adjacent terminal list distribution step in which a second communication terminal, which has been registered as a safe adjacent terminal at least two first communication terminals out of the plurality of communication terminals, distributes an adjacent terminal list including terminal identifiers of the first communication terminals, along with a first temporal key generated by the second communication terminal;

    an adjacent registration information distribution step in which one of the first communication terminals that has received the adjacent terminal list and the first temporal key distributes adjacent registration information generated using a second temporal key; and

    an adjacent terminal authentication step in which the one of the first communication terminals is authenticated when the other one of the first communication terminals that has received both the adjacent terminal list and the adjacent registration information confirms that the terminal identifier of the one of the first communication terminals is included in the adjacent terminal list and confirms that the first temporal key distributed along with the adjacent terminal list matches with the second temporal key used for generating the adjacent registration information.
