A hierarchical blockchain-enabled security-threat assessment architecture for IoV
In Internet of Vehicles(IoV),the security-threat information of various traffic elements can be exploited by hackers to attack vehicles,resulting in accidents,privacy leakage.Consequently,it is necessary to establish security-threat assessment architectures to evaluate risks of traffic elements by managing and sharing security-threat information.Unfortunately,most assessment architectures process data in a centralized manner,causing delays in query services.To address this issue,in this paper,a Hierarchical Blockchain-enabled Security threat Assessment Architecture(HBSAA)is proposed,utilizing edge chains and global chains to share data.In addition,data virtualization technology is introduced to manage multi-source heterogeneous data,and a metadata asso-ciation model based on attribute graph is designed to deal with complex data relationships.In order to provide high-speed query service,the ant colony optimization of key nodes is designed,and the HBSAA prototype is also developed and the performance is tested.Experimental results on the large-scale vulnerabilities data gathered from NVD demonstrate that the HBSAA not only shields data heterogeneity,but also reduces service response time.
