Embodiment Construction

[0047] Based on the scenarios shown in FIGS. 1 to 3 , the method according to the invention is explained in detail in the subsequent figures with the aid of exemplary embodiments, wherein identical components and method steps contain the same reference symbols.

[0048] The core of the present invention is that the new node represented by MESH-AAA in Fig. 4 to Fig. 6 or the function implemented on the node will run as an AAA agent connected between the mesh node and the AAA server.

[0049] The new node MESH-AAA can be realized, for example, on a mesh gateway node GW, which connects the mesh network to the infrastructure network.

[0050] The method of the invention consists in that, after successful authentication of the first mesh node, ie the first communication means MP-A of the new node, the station MESH-AAA stores the key obtained by the AAA server AAA-S or by This key derives the key and causes the key to be distributed to the first communication means MP-A.

Abstract

The invention relates to a method and an arrangement for creating a wireless mesh network in which a new node (or a functionality on a node) is provided that is connected between mesh nodes (MP-A, MP-C) and an AAA server (AAA-S) located in an infrastructure network. Based on basic encoding data that is available to the new node following successful initial authentication of a first mesh node, said new node (or functionality on a node) performs the authentication similar to a proxy server instead of the AAA server, particularly for a limited time, during subsequent authentication attempts.

Description

technical field [0001] The invention relates to a method for providing a wireless mesh network according to the preamble of claim 1 and an arrangement for providing a wireless mesh network according to the preamble of claim 30 . [0002] The present invention relates to methods and systems for providing keys for encrypting messages between nodes of a mesh network. Background technique [0003] A wireless mesh network is a meshed network that is implemented, for example, in a wireless local area network (WLAN). In a mesh network, a mobile node can transmit data from another mobile node to other mobile nodes or to a base station. In mesh networks, very large distances can be spanned, especially in uneven or complex areas. Mesh networks also work very reliably because each mobile node is connected to several other nodes. If a node fails, for example due to a hardware defect, its neighbors look for alternative data transmission paths. Both fixed and mobile devices can partic...
