Communication method, mesh netwrok system and communication terminal
First Claim
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.

Abstract
A communication method in which an operation, such as authentication, required when a new communication terminal participates in a mesh network is carried out in a more efficient manner. A second communication terminal that has already established an adjacent communication link with at least two first communication terminals, out of a plurality of communication terminals, distributes an adjacent terminal list including terminal identifiers of the first communication terminals along with a temporal key generated by the second communication terminal. One of the first communication terminals that received the adjacent terminal list and the temporal key distributes adjacent registration information, which is generated using a second temporal key. The other one of the first communication terminals that received both the adjacent terminal list and the adjacent registration information determines whether the terminal identifier of one of the first communication terminals is included in the adjacent terminal list, and whether the first temporal key distributed along with the adjacent terminal list matches with the second temporal key used for generating the adjacent registration information. If both determination results are affirmative, one of the first communication terminals is authenticated.
