Research on Lightweight Gateway of IoT in Consortium Chain Environment
摘要
Abstract
The distributed and decentralized nature of blockchain technology can effectively address the security challenges faced by traditional Internet of Things(IoT)architectures in terms of device and data security.As a key node in the integration of blockchain and IoT,the gateway faces practical difficulties such as limited computing power and storage resources,requiring lightweight design and im-plementation solutions.In this paper,a blockchain-based lightweight IoT gateway prototype was designed and implemented to address this problem.Firstly,the key data of the link certificate and transaction are filtered and simplified in the gateway based on ChainMaker SPV(Simplified Payment Verification)framework.Secondly,pattern extraction and anomaly detection were carried out from both the behavior patterns of the perception device and the perception data,ensuring device access security and operational safety.Finally,a pruning algorithm was proposed for the Merkle tree stored on the gateway's lightweight node to speed up the verification process for relevant transaction data in the organization.Experimental results show that the designed lightweight gateway has the feasibility of device identity authentication and runtime abnormal behavior detection,and the proposed Merkle tree pruning optimization algorithm can significantly reduce transaction verification latency compared to other methods.关键词
