However, edge computing nodes are vulnerable to various network attacks, posing security risks to data storage and sharing. Moreover, the presence of abnormal vehicles during the sharing process poses significant security threats to the entire network. To address these issues, this paper proposes a novel reputation management scheme, which proposes an improved multi-source multi-weight subjective logic algorithm. This algorithm fuses the direct and indirect opinion feedback of nodes through the subjective logic trust model while considering factors such as event validity, familiarity, timeliness, and trajectory similarity. Vehicle reputation values are periodically updated, and abnormal vehicles are identified through reputation thresholds. Finally, blockchain technology is employed to ensure the security of data storage and sharing. By analyzing real vehicle trajectory datasets, the algorithm is proven to effectively improve the differentiation and detection rate of abnormal vehicles.<\/jats:p>","DOI":"10.3390\/s23104624","type":"journal-article","created":{"date-parts":[[2023,5,11]],"date-time":"2023-05-11T01:37:24Z","timestamp":1683769044000},"page":"4624","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Blockchain-Assisted Reputation Management Scheme for Internet of Vehicles"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0517-7687","authenticated-orcid":false,"given":"Qian","family":"Liu","sequence":"first","affiliation":[{"name":"School of Communication and Information Engineering, Chongqing University of Posts and Telecommunications, Chongqing 400065, China"},{"name":"Key Laboratory of the Ministry of Education on Mobile Communications Technology, Chongqing 400065, China"},{"name":"Chongqing Key Laboratory of Mobile Communications Technology, Chongqing 400065, China"},{"name":"Post Doctoral Research Workstation of Engineering Research Center of Mobile Communications, Ministry of Education, Chongqing 400065, China"}]},{"given":"Junquan","family":"Gong","sequence":"additional","affiliation":[{"name":"School of Communication and Information Engineering, Chongqing University of Posts and Telecommunications, Chongqing 400065, China"},{"name":"Key Laboratory of the Ministry of Education on Mobile Communications Technology, Chongqing 400065, China"},{"name":"Chongqing Key Laboratory of Mobile Communications Technology, Chongqing 400065, China"}]},{"given":"Qilie","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Communication and Information Engineering, Chongqing University of Posts and Telecommunications, Chongqing 400065, China"},{"name":"Key Laboratory of the Ministry of Education on Mobile Communications Technology, Chongqing 400065, China"},{"name":"Chongqing Key Laboratory of Mobile Communications Technology, Chongqing 400065, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"308","DOI":"10.1109\/JPROC.2019.2961937","article-title":"Evolutionary V2X technologies toward the Internet of vehicles: Challenges and opportunities","volume":"108","author":"Zhou","year":"2020","journal-title":"Proc.
