Abstract

As a brand-new network structure, WLAN Mesh network is a distributed network with large capacity, fast speed and wide coverage. However, the security problems caused by the characteristics of wireless connection are not negligible. This paper proposes a new blockchain-based WLAN Mesh design method, including user encryption module, blockchain authentication module and kernel space module. Using the blockchain technology, each user's access authentication request is treated as a transaction, and all authentication records in the mesh network are treated as public ledgers. This method based on blockchain enables secure access to the network and prevents malicious attacks.

Highlights

wireless local area network (WLAN) Mesh network is a wireless broadband access network technology that has been rapidly developed in recent years
The wireless Mesh network inherits the characteristics of wireless Ad-hoc network without center, no infrastructure, multi-hop, self-organization, and it has developed a new architecture to provide IP broadband access
In the wlan mesh network, the mesh ap nodes are connected wirelessly, and the data transmission can be forwarded by multiple hops, making the mesh network more vulnerable to active intrusion, passive eavesdropping, identity forgery and data tampering

Summary

Introduction

WLAN Mesh network is a wireless broadband access network technology that has been rapidly developed in recent years. It does not require a pre-built infrastructure such as a base station, but uses a distributed idea to construct a dynamic self-organized wireless multi-hop network. Kernel space module includes wifidriver and netlink These three modules jointly implement the wlan mesh security access based on the blockchain. All distributed ledgers maintain the network access records of all authentications in the blockchain and make it safer for new users to access the network.The specific architecture of Wlan Mesh manager based on blockchain is shown in the following figure 1
