Research On Blockchain-based Industrial Internet Identification Resolution Security Technology

With the deepening of industrial intelligence and automation,the Industrial Internet,as an important means of traditional industrial transformation and upgrading,has attracted extensive attention.As a key technology of industrial Internet information interaction,identification analysis technology is responsible for the distribution,identification,analysis and routing of device identities.Due to the limitation of traditional network architecture,more and more researches focus on named data network(NDN).However,the NDN-based industrial Internet brings new security challenges to the identity resolution and transmission process.The current solutions rely on key distribution or access control technology,which cannot solve the problem of lack of routing trust in transmission and data leakage risk in security solutions.Therefore,this paper studies a security technology for industrial Internet identification resolution for routing trust issues and security scheme data privacy issues,as follows:1)A lightweight audit scheme based on improved Bloom filter identification resolutionAiming at the main attack problem in the transmission process and the potential risk of data leakage in the security scheme,this paper proposes a lightweight identification analysis behavior audit scheme based on blockchain.This solution uploads the device’s behavior records to the blockchain,and uses blockchain contracts to conduct behavior audits.The audit includes three stages: certification,review,and feedback.At the same time,in order to achieve lightweight auditing,this paper uses an improved Bloom filter to compress the data that is actually stored on the chain.Since the data processed by the Bloom filter is unique and has no characteristics,it can protect the privacy of the original data and compress the data.2)Reputation evaluation scheme based on identification analysis service evaluationAiming at the problem of lack of routing trust,this paper proposes a reputation evaluation scheme based on identification resolution service evaluation.Due to the different network architectures,we adopt a "dual reputation" scheme to add reputation values to the cached content to prevent untrustworthy cached content from spreading on the network.At the same time,the node reputation will be used to determine whether the node is trustworthy,preventing it from sending or attacking other nodes.In order to discover node abnormalities faster,we adopt a reputation calculation method based on service evaluation,and use service evaluation and recent behavior reputation as parameters for evaluation,which can motivate nodes to provide good services and protect data security.3)Blockchain-based Industrial Internet logo resolution audit systemAccording to the proposed logo analysis lightweight audit scheme and the reputation evaluation scheme of logo resolution service evaluation,a block chain-based industrial Internet logo resolution audit system is designed and developed,which realizes lightweight behavior review and reputation evaluation.
