Embodiment Construction

[0048]The embodiment of the present invention selects the associated node based on the degree of trust, and realizes the purpose of two-way authentication between the requester and the authenticator by verifying the signature of the degree of trust. The trust degree is distributed and managed uniformly by the AS. After the requester is authenticated by the AS, the trust degree and related signature information are issued, which are used as the basis for accessing the Mesh network. When a node leaves the Mesh network or is attacked, the AS is responsible for the deprivation or reduction of trust.

[0049] The following embodiments illustrate the two-way authentication process by taking the node access authentication process in the Mesh network as an example, and the specific implementation process is as follows:

[0050] Step 1. The requester selects an intermediate node that interacts with the AS, that is, selects an authentication access node as an intermediate authenticator...

Abstract

An authentication server and a method, a system, a device for bi-authenticating in a mesh network are provided. The said authentication server includes: a credit degree distributing module for determining the security degree of the node based on the received node information of the node which requests for authenticating, and generating a credit degree time stamp after successful authenticating, then signing it and sending it down to the node which requests for authenticating with the identifier of sign arithmetic; a credit degree management module for storing the users identity information of all successful authentication nodes in mesh and the credit degree, signature and time stamp information which are certificated by the authentication server. The authentication server further includes a node status detecting module for detecting whether the nodes in mesh are attacked; a credit degree reducing / depriving module for reducing / depriving the credit degree of the notes when receives a disconnection information or after being attacked. The present invention realizes that each node in Mesh net can select the associated node based on the credit degree, and once realizes bi-authenticating by validating the credit degree signature which is feedback from the associated node.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an authentication server and a method and system for two-way authentication in a mesh network. Background technique [0002] Wireless Mesh (wireless mesh network) network is also called "multi-hop" network, which is a new wireless network technology completely different from traditional wireless network. In a traditional wireless network, a centralized AP (Access point, access point) must first be accessed to perform a wireless connection. In this way, even if two 802.11b nodes are next to each other, they must communicate through the access point. In a wireless Mesh network, any wireless device node can act as an AP or a router at the same time, each node can send and receive data, and can communicate directly with one or more peer nodes. [0003] The wireless Mesh network is different from the traditional BSS (Basic Service Set) in the role division. In the BSS domain...
