A AUTHENTICATION SERVER AND A METHOD,A SYSTEM,A DEVICE FOR BI-AUTHENTICATING IN A MESH NETWORK

摘要

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.
