基于区块链的无线Mesh网络认证机制的研究

RESEARCH ON WIRELESS MESH NETWORK AUTHENTICATION MECHANISM BASED ON BLOCKCHAIN

无线Mesh网络(WMN)由许多网状节点组成,它提供了有效的Internet链接。接入认证安全是WMN快速普及的主要障碍,故提出一种基于区块链的无线Mesh网络认证机制。验证过程只需要比较用户提供的证书计算的哈希值是否与存储在区块链中的哈希值一致,与已有认证机制相比简化了认证流程,减少了认证延迟,提升了认证效率,解决了集中式架构容易导致的单点故障问题,达到分布式认证效果,区块链技术的引入为解决无线Mesh网络中的安全问题提供了新思路。

Wireless mesh network(WMN)consists of a number of mesh nodes,and it provides efficient internet links.The access authentication security is the main obstacle to the rapid popularity of WMN.This paper proposes a blockchain-based wireless mesh network authentication mechanism.The verification process only needs to compare whether the hash value calculated by the user-provided certificate is consistent with the hash value stored in the blockchain.Compared with the existing authentication mechanism,the authentication process is simplified,the authentication delay is reduced,the authentication efficiency is improved.The single-point fault problem easily caused by the centralized architecture is solved,and the distributed authentication effect is achieved.The introduction of the blockchain technology provides a new idea for solving the security problem in the wireless mesh network.
