拜占庭攻击下基于以太坊的智慧工厂安全防御策略
An Ethereum-based security defense strategy against the Byzantine attack in smart factories
摘要
Abstract
This paper proposes an Ethereum-based security strategy to defend the Byzantine attack in the smart factories.Firstly,a reference circle-based hierarchical information flow mechanism is proposed,where the nodes in the smart factory are divided into the many common nodes and the few key nodes.The common nodes evaluate the possibility of the key nodes to behave maliciously,by which attacks from the key nodes are more likely to be unsuccessful.Secondly,a reputation-driven Bayesian inference method where the reputation of nodes,the physical distance between nodes are considered to improve the efficiency of evaluation of malicious behaviors.Finally,a series of simulation experiments are carried out using robotic arms and the simulation results are presented to verify the availability and effectiveness of the proposed method.关键词
