Research On Credible Honeynet Technology Based On Blockchain

The situation of network security has been increasingly severe,and security defense technology is of great significance.Current defense technologies such as firewall technology,intrusion detection technology,and anti-virus technology are usually aimed at reactions after an attack has occurred,which are passive defenses,and have limitations such as delayed defense and difficulty in defending against unknown attacks.Therefore,active defense technology came into being,and its typical representatives are honeypots and honeynet composed of multiple honeypots.However,traditional honeynet usually lack internal communication and are overly dependent on data centers,which have great limitations in large-scale network defense.At present,in response to this shortcoming,some scholars have researched and proposed the concept of a decentralized distributed honeynet.However,the issues of consensus and trust management in distributed honeynets pose major challenges.Blockchain technology can realize the collaborative consensus of multiple nodes in a distributed environment,and has the characteristics of decentralization,which provides a brand-new idea for realizing the security and credibility of distributed honeynets.This article analyzes the research and development status of honeynet technology and the current credibility challenges.On this basis,it researches and designs a blockchain-based trusted honeynet technology to solve consensus problems and trust management issues in distributed honeynets.Firstly,this article designs a trusted honeynet architecture based on blockchain;Secondly,based on this architecture,a fusion consensus algorithm for overlapping information is proposed to build a consensus mechanism for trusted honeynets;Finally,a trusted honeynet based on blockchain is proposed.The trust management mechanism of the honeynet realizes the trust management within the honeynet.In the end,the related technologies and algorithms were simulated and verified on the simulation platform.The main content of this article includes the following points:1)In view of the single point of failure and lack of internal information exchange in traditional distributed honeynets,this article introduces blockchain technology and establishes a consensus mechanism and information management mechanism,and researches and establishes a trusted honeynet based on blockchain Architecture.2)Based on the above architecture,combined with the characteristics of honeynet environment changes,honeypot capabilities,and malicious control,research and propose a fusion consensus algorithm for overlapping information.The algorithm is based on the analysis of trust and similarity,and integrates the honeypot judgment results to form a more global and complete attack knowledge base.3)Aiming at the issue of internal trust management in trusted honeynets based on blockchain,research and propose a trust management mechanism for trusted honeynets based on blockchain.The mechanism scores credibility based on honeypot behavior,and establishes an incentive mechanism based on the score to keep the honeynet environment safe and credible.The simulation results show that the blockchain-based trusted honeynet architecture proposed in this article,as well as its consensus mechanism and trust management mechanism,can achieve a more complete and reliable attack knowledge base,and can realize trust management within the honeynet.Compared with the existing honeynet technology,it shows good effectiveness and superiority in the accuracy of attack detection and the trust management of the honeynet.
