Smart Contract-based Security Architecture for Wireless Mesh Network

Abstract

To improve the security of Wireless Mesh Network(WMN),this paper proposes a Smart Contract-based Security Architecture(SCSA) that integrates blockchain technology.The proposed architecture builds blockchains on routing nodes.Three types of smart contracts are deployed to provide hierarchical management for public keys of nodes,including public key updating,public key cancellation and user access authentication.Also,the Elliptic Curve Diffie-Hellman(ECDH) and symmetric encryption are used to implement secure communication between nodes.Experimental results show that SCSA can efficiently resist node clone attacks or node forgery attacks,key compromise attacks and denial of service attacks,ensuring the security and efficiency of network communication.
