Safe and valid instant authentication method in wireless Mesh network

Abstract

A safe and effective instant authentication method in a wireless Mesh network belongs to a computer network field. The method comprises three stages of preassigning authentication certificate, signing and releasing passport and instant authenticating. In the stage of preassigning authentication certificate, an off-line CA and an authentication center reasonably distribute authentication certificate to guarantee that a local network, an access network authentication center and a mobile terminal hold an authentication certificate released by the off-line CA and the wireless Mesh access point hold the authentication certificate released by the authentication center. In the stage of signing and releasing passport, the local network authentication center signs and releases a passport for the mobile terminal. Finally, the mobile terminal and the wireless Mesh access point realize the safe and effective bidirectional instant authentication. The method according to the invention has the advantages of full use of common key base facility resources which are widely disposed, resource consumption reduction in roaming authentication, delay reduction in roaming authentication, without complexity in using the common key base facility certificate, and facilitated disposition and realization.

Description

technical field [0001] The present invention relates to an instant authentication method for wireless Mesh network roaming, in particular to an instant authentication method for wireless Mesh network roaming based on identification certificate pre-allocation, which can be used for security between a mobile terminal and a wireless Mesh access point in a wireless Mesh network An effective two-way instant authentication belongs to the field of computer networks. Background technique [0002] In wireless Mesh networks, most of the access authentication methods for mobile terminals roaming into the access network that have been deployed and implemented require the interaction of authentication information between the visiting network authentication center and the local network authentication center. First, the visiting network authentication center transmits the authentication information of the mobile terminal to the local network authentication center through a secure channel. ...

AI Technical Summary

Problems solved by technology

The secure communication between the visited network authentication center and the local network authentication center consumes a lot of network resources and increases the delay of roaming authentication

[0003] The current instant authentication method does not consider the full utilization of the widely deployed public key infrastructure resources, the algorithm is complex, and the implementation is inconvenient
